Re: Rocky Mount Flyrock Incident
Corretive Actions Taken
Final Report
Dear Mr. Davis,
RECEIVED:
DEHNR s:
FEB 9 1995
LAND QUALITY SECTION
Pursuant to Mr. Gardner's correspondence dated September 29, 1994 granting written
approval to resume blasting at our Rocky Mount Quarry following a flyrock incident on
September 8, 1994, this report will serve to address the corrective actions taken since then to
prevent further incidents from occurring. Our outside blasting consultant, ICI Explosives, has
been onsite since the incident took place and has come up with certain recommendations for your
review and approval. These are included in this submittal, along with copies of all blast reports
and seismograph recordings for blasts conducted during this period.
Before a discussion of the findings, I would like to briefly summarize the circumstances
that resulted in the flyrock incident on September 8, 1994. A production shot containing thirty
six (36) holes was initiated concurrently with a toe shot containing twenty (20) holes in the floor
of the pit. The production holes were drilled on a 7' x 10' pattern and the toe shot was drilled
on a 6' x 6' pattern. A total of 5,026 lbs. of explosives were used, the bulk of which was ANFO.
Of the total, 170 lbs. was consumed in the toe shot, or roughly eight (8) lbs. per hole. The
production shot was initiated with a redundant non -electric system while the toe shot was initiated
using an eletric system.
After initiating the blast, flyrock was observed to have crossed highway 97 and struck a
pine tree in the front yard of the Winstead property. Upon futher examination on September 10,
1994, it was discovered that a flyrock had also knocked a hole in the wall of a storage shed behind
the Winstead house. Repairs were promptly made to this structure.
A thorough investigation of the incident was conducted by Teer, Vibra Tech, and ICI
Explosives to determine the cause and souce of the flyrock. During this time, blasting at Rocky
Mount was suspended while awaiting the outcome of the investigation and the submittal of those

findings to the your department for review and approval. This report was submitted on September
19, 1994 by Mr. Steve Edgerton and myself. Based upon the findings from this investigation, it
was determined that the flyrock was generated from the toe shot as the result of insufficient
burden. Verbal approval to resume blasting was received on September 26, 1994 and was
followed by written approval dated September 29, 1994.
As a result of the flyrock incident, the Teer Co. and its consultant have reviewed the
various factors which affect blasting results. By making adjustments to these factors, specifically
pit layout, timing sequences, and elimination and/or handling of toes, we feel that we can avoid
further flyrock incidents. These factors, along with corrective action(s) taken and adjustments
made to enhance blasting procedures, are detailed below.
Pit layout and development at Rocky Mount have historically progressed away from
highway 97. Benches have generally been developed in an east -west orientation with the mining
faces driven back from the northern to the southern end of the pit. Although the pit configuration
is excellent, the typical blast direction has been predominately to the north. This has indirectly
created the potential for problems to arise if a production shot malfunctions during initiation.
Since the Sept. 8th incident, the existing configuration has been reviewed and a decision made
to reorient the mining faces. Beginning in December, 1994, sinking operations commenced at
the southernmost end of the pit to begin development of the main mining face so that it will
be driven from the southern to the northern end of the pit. In other words, the predominate
blast direction will be to the south, away from any dwellings. I believe that this adjustment to the
blasting program will have the most positive effect overall.
Another factor that has been thoroughly scrutinized is the surface and in hole timing
sequences. As you will recall, we had an earlier flyrock incident that occurred on November 1,
1993 which was the result of a "cutoff". This situation occurred due to the use of a single path,
non -electric system that somehow was severed during the ignition sequence. After this incident,
it was decided to go to a redundant, non -electric system to prevent the likelihood of "cutoffs" from
occurring again. The only redundant system available was a 25 millisecond surface delay which
we employed with 475 to 500 millisecond down the hole delays. This effectively solved the
"cutoff" problem but in the process created a more onerous one - the creation of toes.
In our investigative report to your office on September 19, 1994, we felt that this delay
sequence was too slow, in particular the 475 millisecond down the hole delay, to prevent toes
from occurring. To some degree, we still feel that this is still the case. However, we have
experimented with the timing on both the surface and in hole delays and now feel that, in most
instances, we will be able to use a redundant 17 millisecond surface delay coupled with a 475 �l-
millisecond in hole delay. This redundant 17 millisecond delay has just recently become
available for our use. This adjustment will allow us to achieve better floor separation and
breakage by going with a faster timing sequence down a line of holes. In other words, ten holes
in a line with a delay sequence of 17 milliseconds/hole will shoot 80 milliseconds faster than the
same ten holes with a delay sequence of 25 milliseconds/hole. An adjustment has also been
made to the timing between lines of holes as a result of going to the 17 millisecond delay. In
the past, the second line of holes was initiated off the second hole on the front line of holes. That
meant that subsequent lines of holes were initiated at 92 millisecond intervals after the shot was
ignited. Use of the 17 millisecond delay will mean that subsequent lines of holes will be initiated

at 76 millisecond intervals. The duration of the entire shot will therefore be shorter and will
cause the shot to generate less vibration. Another benefit of this adjustment will be that by
speeding up the timing, the front line of holes will create a buffering effect for the second line of
holes, therefore reducing the risk of flyrock from the second line of holes. Essentially, if the blast
is shot slower, the front line of holes could be fully relieved before the second line is ignited.
This could result in flyrock from the second line since there would be no burden, to speak of,
to act as a buffer.
Included in this report are five (5) different delay sequence diagrams that ICI Explosives
has recommended to be used at Rocky Mount Quarry. These sequences represent two different
blast scenarios that we will normally employ in our blast program. They are listed below in order
of the anticipated frequency of their use.
1) Open face / open corner
17ms / 76ms
2) Open face / open corner
25ms / 67ms
3) Open face / box cut
25ms / 42ms / 84ms
4) Open face / open corner
17ms / 59ms
5) Open face / box cut
17ms / 25ms / 76m
These sequences are the typical conditions to be encountered in the pit and represent what
ICI feels are the most appropriate standards to follow. Sinking shots and other specialty shots will
be specifically designed by ICI Explosives to take into account any atypical or adverse conditions
which will require special treatment.
Teer and ICI have also spent considerable time in trying to find a solution to our recurrent
toe problems that result from production blasting. As previously mentioned, last September we
felt that a good deal of our toe problems were the result of the 475 millisecond in hole delays that
we were using. To some degree, we still feel that way. However, ICI's philosophy has been to
have the whole shot "lit" before the shot moves out. In order to do this, we felt that it was
necessary to continue using the 475 ms delays. Therefore, we evaluated what adjustments had
to be made to maintain this strategy. As a result, we changed the bottom charge in the hole
from Apex Ultra to Superfrac 6000. By changing to a higher energy explosive and continuing
to use the 475 ms in hole delay, we have achieved much better floor shear and separation. In the
past, we used three (3) sticks of 3-1/4" x 16" of Apex Ultra, obviously with limited success.
Currently, the bottom of each hole is loaded with two sticks of Superfrac in the subdrilling,
followed by a one (1) lb. cast booster at floor level, followed by one (1) stick of Superfrac. This
adjustment has so far minimized the creation of toes.
As a result of the flyrock incident last September, we have also made it policy that all toe1
shots be covered with a three (3) foot minimum thickness of screenings to avoid flyrock. This
policy has also been applied to any specialty shots (i.e., sinking shots, leveling shots, etc.) on
the north end of the pit nearest to highway 97. This corrective action has already been used
on the toes shot since the flyrock incident and also on a sinking shot on the north end of the pit.
The results were very satisfactory.
In conclusion, I believe that the Teer Co. and ICI Explosives have worked very diligently
to take whatever corrective actions have been necessary to prevent further flyrock incidents from

occurring. I have reviewed the report submitted by ICI Explosives and therefore tender the
following recommendations, in summary form, for your review and approval.
1) All future shots are to be video taped
2) All specialty shots will be covered with a blanket of screenings
3) Stemtite blasting plugs should be used where applicable
4) Blast designs will be mutually agreed to by Teer and its blast consultant
5) Blast performance of each blast will be reviewed by the Teer quarry 7
superintendent and the blaster of record Ail
6) Monthly reviews of the blasting program will be held and all blast r
information from the preceding month will be discussed
4ur"r"c�
In addition to the foregoing, Teer is willing to continue using ICI Explosives as its
contractual blasting consultant for the foreseeable future.
I trust that this information meets with your approval. If you have any questions, please
don't hesitate to call. If technical questions arise regarding the proposed timing sequences, I
would suggest that you contact Mr. Lynn Long with ICI Explosives. He can be reached at 1-800-
552-8527 box 609. Thank you for your consideration in this matter.

LAND QUALITY SECTION
This report contains the original seismic data from blasting associated with the Rocky
Mount Quarry. Thirteen blasts, dated November 3, 1994 through December 22, 1994
are included.
The maximum value of the recorded peak particle velocity for this series of blasts was
0.28 inches per second (ips), significantly below the established criteria for ground
vibration as recommended by the United States Bureau of Mines (RI-8507: November,
1980), Structure Response and Damage Produced by Ground Vibration From Surface
Mine Blasting. This value, recorded from the blast dated December 14, 1994,
represents 28 percent of the allowable vibration limit as stipulated by the North
Carolina Mining Act of 1971.
The maximum recorded air blast level for this series of blasts was 125 decibels (dB),
or 0.00516 pounds per square inch (psi), for the blast dated December 5, 1994, which
represents seventy-one percent of the 128 dB limit stipulated by the North Carolina
Department of Environment, Health, and Natural Resources.
Should you have any questions or require additional information regarding the
contents of this report, please do not hesitate to contact me at once.

Dear Mr. Bolling:

This report contains the original seismic data from blasting associated with the Rocky
Mount Quarry. Thirteen blasts, dated September 6, 1994 through October 26, 1994 are
included.
The maximum value of the recorded peak particle velocity for this series of blasts was
0.11 inches per second (ips), significantly below the established criteria for ground
vibration as recommended by the United States Bureau of Mines (RI-8507: November,
1980), Structure Response and Damage Produced by Ground Vibration From Surface
Mine Blasting. This value, recorded from the blast dated October 24, 1994, represents
eleven percent of the allowable vibration limit as stipulated by the North Carolina
Mining Act of 1971.
The maximum recorded air blast level for this series of blasts was 136 decibels (dB),
or 0.01830 pounds per square inch (psi), for the blast dated September 8, 1994, which
represents two hundred fifty one percent of the 128 dB limit stipulated by the North
Carolina Department of Environment, Health, and Natural Resources.
Should you have any questions or require additional information regarding the
contents of this report, please do not hesitate to contact me at once.

(* = denotes fields where input data is needed)
Permit No.*: 33-13
Permitteet: Nello L. Teer Company
Mine Nara : Rocky Mount Quarry
Blast Report No.*: 52 Date of 31astt : 09/08/94 Time of Blast*: 04:59 PM
Peak Particle Velocity Check:
D = Distance to closest offsite occupied structure lft}: D* = 1200.0
W = Maximum pounds of explosives per delay {pounds) : W* = 139.6
SD = Scaled Distance: SD = DjW'0.5 SD = 101.5601
V = Peak Particle Velocity {inches per second): V = 160 (SD)"-1.6 V = 0.098
(tmax, limit in mining permit is: V = 1.0 ips)
Based on known distances from the blast to the seismograph and any additional location,
the expected vibration level can be estimated at the second location as follows: 16 � o. 01 ; f4 ME*PA �
V = Particle velocity measured by the seismograph (ips) : V* = 0
DS = Distance from blast to seismograph (ft) : DSt = 0
d = Distance from blast to second location (ftI : d* = 0
PPV = Theoretical peak particle velocity at the closest offsite occupied structure (ips) :
PPV = V{DS f d) "1. 5 PPV = so
Airblast (Overpressure) Check:

GO TO PAGE 2 FOR EXPLOSIVES COLUMN CHECK

Explosives Column Check:
(this is a very approximate method based upon numerous assumptions;
specific densities may vary greatly depending upon the type and manufacturer
of the explosive products used in the shot; must consider each explosive used;
refer to Dupont Handbook for actual SPD, otherwise use the following:)
Assumptions: If 'straight" emulsion is used, use SPD (specific density) = 1.20
(per Ireco) If a 'blend/slurry, is used, use SPD (specific density) = 1.25
If 'straight' anfo is used, use SPD (specific density) = 0.85
Ratio between explosives: Total pounds of Explos. 11* = 3400
Total pounds of Explos. #2 [use'0.1' here if only have one explos.)* = 936
Ratio between explosives = 3.632479
Average pounds of explosives used per hole (pounds)' = 135
Breakdown of average pounds of explosives per hole due to ratio:
Explosive #1 = 97.83529
Explosive #2 = 37.16471
SPD : Specific densities for each explosive. SPD for Explos. #1* = 0.85
SPD for Explos. #2 (use'0.1' here if only have one explosive)* = 1.2
HD = Hole Diameter Used in Shot (inches) : HD* = 4
LD = Loading Density (pounds per foot of column): LD = SPD(.34) (HD) "2
LD for Explos. #1 = 4.62
LD for Rxplos. #2 = 6.53
Explosive column height for each explosive (feet): Explos. #1 = 21.15B15
Explos. 12 : 5.693123
Total explos. column height = 26.85127
Stewing height used in shot (feet) * : 5
Total height of explosive colum(s) and stemming in the hole = 31.85127
Total depth of hole denoted on the blasting report for the shot in question* _ - 34

RE: Report on Rocky Mount Quarry
Dear Jim,

LAND QUALRY SECTION
The following is our report on the Rocky Mount Quarry.
We have reviewed the blast results for the period September 27, 1994 to January 24,
1995,
During this period we have been directly involved in all blasts conducted at the Rocky
Mount Quarry.
In accordance with the recommendations made in September 1994, all shots have been
video taped to develop a record of performance and containment of blasts.
All toe shots were covered with quarry fines (screenings) to confine upward movement.
This has been effective in improving confinement of the toe areas shot.
We made a recommendation to change to a higher energy bottom load in holes, to help
alleviate the high bottom or toe problem. This bottom load of 3 cartridges of 3 &1/4 by
16 Superfrac 6000 has improved shear at floor level, thus reducing the incidence of
development of toes,
During sump development in the North end of the pit a blast was structured to open the
sinking area that incorporated a good balanced powder distribution with a complex, but
very effective delay sequence.
During this blast, fired on December 14, 1994, seismic results were a peak particle
velocity of 0.28 and a peak overpressure of 118 Db. However due probably to geology the
fre uencie were in the ran a of res onse of residential structures.

VIA D COM

Also the sinking shot was blanketed with approximately 6 to 7 feet of screenings to reduce
upward, expulsion of the fragmented rock when the shot was fired. This shot was very well
controlled with good containment of upward movement.
During December, development was started in the South end of the pit to reorient most of
the working faces to point South away from Highway 97 and the residences located there.
This work is progressing very well at this time.
On reviewing the video records for performance, all shots show good containment with Jo,)
the exception of one which had gas vented in a westerly direction, Rock that was expelled
during this gas venting remained on the quarry floor and was not ejected above the bottom
bench level of the quarry. ViA�'�
t3&
This was caused by an undetected parting joint in the rock. Subsequent shots fired in this
area were examinedumd the parting joint did not have further influence on gas escape
during the later blasts.
The Rocky Mount Quarry has been using Stemtite stemming plugs to improve
confinement of the explosive energy during blasting. This technology is very effective in
reducing air blast and flyrock while aiding in fragmentation and explosive effect in the
blasts.
On reviewing timing, we see that a correlation between geology and timing that varies in
different areas and different directions of the pit.
We have introduced other initiation products with different delay timing, such as the 17ms
Handidet, and different delay sequences to help in adaptability as geology changes. Also
all non -electric shots have been a two path redundant system.
At your request, we have instituted a review of all blast records, seismic records, and
videos with the Superintendent.
Also if any peak particle velocities exceed 0.15 or if any peak overpressures exceed 120
Db we will advise you and develop a strategy to maintain these readings below 0.15 p.p,v
and below 120 Db p.o.p,
Upon reviewing the blasting program that we have conducted at Rocky Mount, in
cooperation with the Teer personnel there, we offer the following recommendations for
your consideration.
1, Continue to video all shots. This will provide us with a valuable tool and record to
continuously work to improve the safety and performance of the blasting program at
Rocky Mount,
2. Cover all specialty shots with quarry fines ( screenings ). Such specialty shots will
include, all toe or leveling shots in the pit and sump or sinking shots located in the North
end of the pit.

I The continued use of the Stemtite stemming plugs to minimize the probability of
stemming ejection.
4. The continued use of a blast design that incorporates a balanced pattern of burden and
spacing in conjunction with a high energy bottom load to minimize development of toes.
The present pattern of 7 x 10 with the high energy bottom load of Superfrac 6000 is
performing well in the denser disjointed gray granite. However, a wider pattern would
perform well in the finer laminated pink metamorphic granite also encountered in the pit.
5. The introduction of 17 ms and 25 ms Handidet initiation systems to provide
adaptability in the delay timing as geological changes are encountered.
We see improved control and fragmentation in areas of highly disjointed, blocky material
when using the faster timing between holes, such as the 17 ms delay. The faster timing
allows the explosive charge to work better on the blocky material before it is moved out
by the energy from a previously delayed charge. As would be the case with a slower
timing of 25 ms or 42 ms between holes.
We have included some useful delay patterns with this report.
6. Review of the blast performance, on the day of the blast, through a visual observation
in the pit and playback of the video, by the blaster in charge and the quarry superintendent
immediately after the blast.
The purpose of this daily review would be to determine if immediate changes should be
made prior to the next blast.
7. A monthly review of the blasting program, including blast reports, seismograph
reports, and the video records by a joint team consisting of the Teer Company
superintendent, pit foreman, and ICI personnel ( blasters, operations manager, and/or
technical representative.
The purpose of the monthly reviews would be long term improvement of performance in
control and fragmentation. During these reviews the team would fine tune the blasting
program from review of seismic results, any gas venting, any geological changes noted or
expected, rock movement during the blast. and by observation of fragmentation
performance.
8. Team development of a blast design for specialty shots such as sump development.
All of these recommendations are geared toward continuously improving the safety and
performance of the blasting program at Rocky Mount.
Sincerely,
6;-1
Lynn Long

Enclosed is the Masterdet initiation pattern used. Robert Star and I concurred with the
recommendation of Lynn Long, Senior Technical Representative ICI Explosives Eastern
.Region, that the shot be,designed for a powder factor of 1 lb of explosive per ton.
Because of the wet conditions PowerAN 6000(with Apex 1210) was the explosive used.
PowerAN 6000 has a density of 1.28 g/cc. and loads at 10.88 or 11 pounds per ft in a 5
inch diameter borehole. PowerAN 6000 is pumped through a hose from a bulk truck.
The nearest off site house to the blast by your estimate was 750 ft. To keep safe levels
of vibration for this house using a combination of Velocity and displacement with an
average hole depth of 43 ft. meant the holes had to be decked to reduce the pounds of
explosive per delay. A 43 ft, hole with 10 ft. of stemming and a 5 ft. deck, using half inch
stone, allows two 14 ft. decks of explosive at 154 lb per deck. Each deck contained 4 lb
of Pentex boosters.
The measured seismic results and overpressure were .28 Peak Particle Velocity at a
predominate Hertz of 5 and 118 decibels on an overcast day with a strong inversion.
These results are well within the safe limits for a plaster constructed house.
The cover of 6 to 8 feet of quarry fines on the shot contained any fly rock potential.
Because of the number of times the bulk truck hose had to go in and out of the holes the
shot was very slow in loading. Robert Star and I want to thank you for your
understanding in letting us guard the shot overnight and wire the circuits and cover the
shot the next day before blasting.

V
rF- . ,IT! f sa s

it is always a pleasure to work with a well run first class operation.
Have a merry Christmas and Happy New Year!
Very truly yours,
Dan McCutchen

Re: Flyrock Incident at Teer Company's Rocky Mount Quarry
Permit No. 33-13, Edgecombe County, NC
Dear Mr. Davis:
As you are aware, our Rocky Mount Quarry experienced a flyrock incident at 4:59 pm
on Thursday, September 8, 1994. Your office was notified by FAX on Friday, September 9,
1994. The shot consisted of thirty six (36) production holes and twenty (20) holes drilled in a
toe just to the left and at the base of the wall. The production holes were drilled on 7' x 10'
burden to spacing pattern and were 30' to 32' in depth. The toe was drilled on a 6' x 6' burden
to spacing pattern and were 6' deep. In addition, a large boulder was also shot during the same
initiation sequence to crack it.
The shot was loaded with 5,026 lbs. of explosives consisting of 3,550 lbs, of ANFO, 936
lbs. of wet hole explosives (3 x 13 AP), 440 lbs. of bottom primer (Apex 3-1/4 x 16), 64 lbs.
of top primer (2 x 8), and 36- 1 lb. boosters. The production shot averaged twelve foot (12')
of stemming on the front line of holes and six foot (6') on the back lines. Of the total poundage
of explosives, 170 lbs. was consumed in the toe shot. The holes in the production shot were
initiated using a redundant non -electric system. The toe shot was initiated with electrical caps
with sufficiently spaced timing so that a maximum of 34 lbs. of explosives were being initiated
per delay in the toe shot. The production shot contained approximately 140 lbs. of explosives
per delay. The closest off -site occupied dwelling is approximately 1200 feet from the shot
(Winstead residence) where the flyrock landed and where the seismograph was monitoring.
Mr. Jerry Bass, Teer Company's Pit Foreman, supervised the loading of the shot and was
responsible for wiring it in, or in the case of non -electric, making the appropriate connections.
He also set up the seismograph at the Winstead house to monitor and record the peak particle
velocity and air blast generated by the shot. When the shot was initiated, Jerry observed flyrock
landing on the Winstead property. On Friday morning, September 9, 1 was notified of the
incident by Mr. Clarence Bolling, our Rocky Mount superintendent. At that time, I dispatched

Steve Edgerton to the site to investigate the incident and to notify your office of the problem.
Vibra Tech was also notified at this time and was requested to perform an evaluation of the
incident on Monday, September 12.
As a result of the investigation on September 9, 1994, it appeared that there was some
minor damage to the Winstead property as a result of the flyrock. This damage included
knocking a couple of two inch tree limbs out of a pine tree in the front yard of the Winstead
residence. Subsequent investigation on September 10, 1994, by the Winsteads, revealed that a
rock had knocked a hole in a wash tub hanging on the Winstead storage shed and into the wall
of the shed behind the wash tub. Repairs have been initiated at the Winstead property and
should be completed within the week. In conversations with Mr. Winstead it is apparent that
he is not aware of any other damage as a result of this incident.
The Winsteads have complained in the past about structural cracks in the brick veneer
on their house, cracks in concrete slabs and various other items. These complaints have been
investigated in the past years and it has been determined that they are a result of settling
foundations and not from the blasting operations conducted at Rocky Mount Quarry. As a part
of Rocky Mount Quarry's blasting program, the Winsteads are called prior to the blasts so that
they will not be surprised by the vibration or the air blast. Pursuant to the Winsteads' wishes,
we will continue to contact them via telephone. In addition to this, all shots are monitored at
the Winstead residence with a representative of Teer Co. going to the residence to set up the
seismograph and monitoring the shot. Should the Winsteads be outside of the house and away
from the phone, but in the yard where the Teer representative monitoring the shot can see them,
we notify the Winsteads in person of the upcoming shot.
Teer has always had a good working relationship with the Winsteads and we appreciate
their patience and understanding. Teer will continue to do everything in their power to see that
incidents such as this do not happen again.
On Monday, September 12, ICI Explosives and the Ensign - Bickford Co. were asked
to investigate what cause(s) led to the occurrence of flyrock from this particular shot. Their
individual reports are included in this report to your office.
From what has been ascertained, it is evident that the toe portion of the shot
generated the flyrock that hit the Winstead property. One of the holes in the toe may have
been adjacent to some loose or highly fractured material. Upon detonation, some of the
explosive force followed the path of least resistance, causing some of this loose material to be
thrown from the pit and onto the Winstead property. An aggravating factor was that the toe
holes were the first holes to be initiated in the blast sequence. This precluded the production
shots from having a dampening, or blanketing, effect on the toe holes. If the production holes
had been initiated a few milliseconds before the toe holes were fired, a blanket effect could have

Mr. Tracy Davis
September 19, 1994
Page 3
been realized.
There are several factors which substantiate the theory that the toe shot caused the
flyrock. The first of which is the vibra-tech shot analysis report prepared by Jay Rodgers of
Vibra Tech. A close examination of this report reveals that the air blast was 138dba which is
not in compliance with the permit and is louder than a normal shot for this site. Air blast is
typically caused by a loss of explosive energy to the atmosphere. This can be a result of joints,
fractures, voids, reduced burden, cracks or insufficient stemming of the blast holes. The rock
typically absorbs this energy when it is being broken apart thus dampening the air blast. Should
there be an insufficient amount of rock to absorb the energy the force of the blast will escape
into the atmosphere causing an excessively high air over pressure reading or air blast. In
conversations with the foreman, driller and superintendent, it does not appear that any unusual
factors such as those listed above were encountered in the production shot which would have
caused the high air blast readings and flyrock. If a lack of stemming had been the cause of the
air blast and flyrock it would have manifested itself visually by creating what is known as a
"blow-out", which looks like a column of smoke or dust rising vertically from the shot. This
occurs when there is insufficient stemming in the hole to contain the blast energy and the energy
producing gases escape through the opening of the blast -hole. This also will create flyrock and
excessive air blast. Mr. Bolling, the site manager, witnessed the shot and stated that he did not
observe any blow -outs in the shot. Therefore, if no blowouts were observed in the shot and no
unusual cracks, fractures, or voids were encountered while drilling the shot, it stands to reason
that there must have been reduced burden, evidently in the toe, which allowed the explosive
energy to escape. As mentioned earlier, if the holes for the toe shot were drilled near fractured
material this would result in reduced burden which would allow the explosive energy to escape
creating air blast and flyrock.
Another factor which supports the conclusion that the flyrock was generated from the toe
shot is the distance calculation based on the seismic monitoring data. From the calculations
generated by Jay Rodgers of Vibra Tech it appears that the source of the air -blast was
approximately 1200' from the seismograph and the seismograph was located in the incident area.
Since air blast and flyrock often are associated with each other it is reasonable to assume that
they both originated in the same area. This distance, when measured off of the plans, correlates
well with the location of the toe shot.
At the same time the production and toe shots were initiated, a boulder shot was also
initiated. While the boulder shot was initially considered as the source of the air -blast and
flyrock, its location and condition after the shot indicated that this was not the source. The
boulder was located some 1400' from the shot which does not match the calculation of where
the source of the air -blast was. The boulder shot was designed to simply split the boulder into
and from its appearance after the shot it appears that this is what occurred, with very little loss

of material, (ie. it appears that the boulder was sliced into with a knife and not pulverized).
While examining the boulder note was made of any fractures joints or possible planes of
weakness which could have contributed to the incident and none were observed. Based on these
observations and calculations the boulder shot was eliminated as a possible cause.
Scaled distance calculations based on the lbsldelay of explosive and the distance to the
nearest occupied dwelling, the Winstead residence, were performed to ensure compliance with
standard safe blasting practices. Based on these calculations the production shot had a scaled
distance of 101.42 and the toe shot had a scaled distance of 205,80. Even if two of the
production holes overlapped and went off at the same time, due to cap scatter, the scaled
distance would still yield 71.7. The industry standard for a safe shot is a scaled distance of 50
while Teer Co. typically tries to have a scaled distance of no less than 60. Even in a worst case
scenario it appears that the shot was conservatively loaded to reduce ground vibration felt by
neighbors. The higher the scaled distance the lower the amount of energy available to vibrate
a structure, thereby reducing the ground vibration at the structure.
A review of the blast diagram and the delay pattern for both the production and the toe
shot does not reveal any deviation from other shots which might explain why the incident
occurred. A review of the timing for the shot does not reveal an opportunity for any excessive
amount of cap overlap which would result in more than one hole shooting at one time. The
production shot pattern is essentially the same as the pattern which has always been used a 7'
burden and 10' spacing.
Based on the above information Teer, Vibra Tech and ICI explosives have all concluded
that the toe shot was the source of the air blast and the flyrock. With this information, Teer and
its consultants have developed some recommendations which are being tendered for your review.
These recommendations will be implemented immediately upon your review and approval for
the resumption of blasting operations at Teer's Rocky Mount facility.
Since the flyrock incident that occurred in November 1, 1993, which was the result of
a "cutoff" in a majority of the production holes in one shot, it was decided to go to a redundant,
non -electric detonating system to prevent a similar situation from occurring again. At that time,
the only redundant system available was one that employed a 25 millisecond surface delay and
a 475-500 millisecond down hole delay. However, since going to this system, we have
experienced an increased amount of toe problems as a result of production blasting with this
delay pattern. It appears that the 475 to 500 millisecond down hole delay to light the entire shot
is too long a time period. We have found that delays in excess of 375 milliseconds are
inaccurate from a timing standpoijnt. Also, we feel that the 25 millisecond delay (surface)
between holes is to short a period of time to minimize the creation of toes.
Since "shooting" toes are less predictable than production shots, it is desirable to minimize the
potential for creating toes at the outset. Another manufacturer of blasting caps

Mr. Tracy Davis
September 19, 1994

which incorporates a redundant system has recently come out with different delays which are
closer to the delay system previously used at this site. Since the delay pattern used prior to the
November 1, 1993, incident did not yield toe problems, it is recommended that Rocky Mt. go
back to the earlier delay pattern with a redundant system, since these delays are now available
in a redundant system. This should lessen the likelihood of developing toe problems as well as
incorporating a redundant system into the shot which will lessen the likelihood of having a cutoff
on the shot.
AfIn the event that toes are encountered in the future the following procedures will be
conducted to lessen the possibility of the toe shot producing flyrock and excessive air blast:
• Once the shot is loaded and connected a blanket of screenings a minimum of 3'
thick will be carefully placed on the toe shot to buffer the shot. This blanket will
extend a minimum of one hole spacing in all directions around the loaded holes.
This should effectively reduce the chance of any materials being thrown from the
shot because one hole was drilled next to fractured material with insufficient
burden. The thickness of the blanket is not an arbitrary number. Included in the
appendix of this report is an analysis and chart which will aid the operation in
determining the amount of cover to be used on toe shots.
The driller will keep written logs of all holes drilled for toe shots, making note
of any incompetent rock. The foreman will be made aware of these conditions
and no holes will be loaded in less than competent material. Holes will be drilled
on the same pattern and spacing around the outside of the toe shot to ensure that
there is competent material around the toe. If during this drilling process
fractured or broken materials are encountered the blast holes in the toe shot will
be appropriately reduced. This should reduce the chance that a hole will be
loaded which is next to fractured or broken materials. All holes which are drilled
outside of the toe shot will be immediately backfilled with drill cuttings to ensure
that they are not accidently loaded.
The timing of all future blasts will be designed so that the production shot will
be initiated prior to the toe shot. As discussed earlier this will create a situation
in which the production shot will act as an additional blanket to reduce the
possibility of flyrock leaving the blast area.
Rocky Mount will undertake actions to reorient its blasting so that any materials
which may inadvertently become airborne will not travel in the direction of the
Winstead residence but in the direction of the plant stockpile and pond area. This
reorientation of the shots will take some time because of the pit benches and their
present orientation. This will be accomplished over time and will add a greater

safety factor to the blasting program at Rocky Mount.
CONCLUSION:
Teer has actively investigated the flyrock incident of September 8, 1994, and feels that
the cause of the incident was the toe shot. Once the cause of the incident was determined a
thorough investigation into what could be done to alleviate the cause in future blasting operations
was performed. Teer feels that the above outlined procedures should eliminate flyrock
associated with toe shots. As always, Teer is'actively striving to institute the safest possible
blasting techniques into its operations.
As you are aware Rocky Mount Quarry is presently unable to shoot until you and your
staff have reviewed and approved the above report. Your prompt review of this report would
be greatly appreciated since we are presently in the peak of our production season. Teer also
realizes that a thorough examination of the data is needed to properly assess if all of the issues
have been adequately addressed. If you or your staff should have any questions please do not
hesitate to call me at 919-380-2612.

Dear Mr. Edgerton:
803-548-3066 FAX [phone]
This letter is in reference to our meeting yesterday at the Rocky Mount Quarry
regarding the flyrock incident of September 8, 1994.
I have examined the blast site, reviewed the blasting records and spoke to Mr. Boling
and Mr. Bass: It is the opinion of everyone, on site at the time of the blast, that the
source of the flyrock material was a toe shot on the floor of the pit tied into the
production blast. Based on the information provided, I agree that the toe shot most
likely produced the flyrock. The toe in this case was a ramping area of the pit floor
caused by roughly horizontal joint idifaces in the rock mass.
During our meeting' Mr. Bass suggested covering all future toe shots with screenings,
so as to prevent flyrock as wellas' reduce air blast. It has been my experience, on
similar 'construction blasting site's, where no amount of flyrock is acceptable, that
covering the blast area with approximately 4 to 5 feet of clean material is very effective
In preventing flyrock and excessive air blast. If these precautions are taken. on all
future toe shots, material should be contained within the blast area.
I have included the blast report form and our computer analysis of the seismograph
record. If you require additional'information, please don't hesitate to contact me.
Sincerely, .

903-548.1066 FAX [phone]
This letter Is in response to your request for more detailed information concerning the amount of
screenings material required to prevent flyrock on all future toe shots at the Rocky Mount Quarry.
Proper blast design Is the primary method for avoiding flyrock, but good design cannot completely
eliminate it. It has been recommended -that screenings material be placed on all future toe shots In
order to control flyrock occurrences. I have performed Calculations intended to establish the amount of
screenings necessary to confine a glveri blast design. These calculations assume no delay overlaps due to
poor design, cap scatter, or propagation.
Stemming confinement evaluation uses explosive diameter, energy, and density with stemming length to
derive a numerical indicator of flyrock occurrences. Stemming confinement, or scaled depth of burial,
greater than 1.4 should typically be used In non caprock applications. Stemming confinement less than
1.4 may not provide adequate confinement and can produce flyrock.
The attached spreadsheets contain the results of my evaluation of various blast designs with explosives
commonly used'at the Rocky Mount Quarry.. To determine the minimum amount of screenings required:
1. 'Choose the spreadsheet for the explosive being used,
2. 'Locate the first non -shaded cell right of the explosive diameter.
3. Read the stemming value from the'top of that column.
4. From this, subtract the amount of sfemming In the rock used for the blast.
S.- The remainder or 3 feet, whichever Is largest, Is the minimum amount of screenings to
be used to cover the blast. '
A stemming •confinement threshold of V.4 is derived from average conditions. Benchmark Materials
should carefully observe future toe shots to determine whether refinement of this number is warranted
by the response of the rockmass at the Rocky Mount Quarry.
Should you have any questions concerning this report or require additional information', please contact
meat once.

Teer Quarries
RE: Recommendations for Teer Co., Rocky Mount Quarry
Mr. Sprinkle,
Don Nickell and myself have reviewed the situation at the Rocky Mount Quarry,
concerning the incident where rock was ejected born the pit onto the adjacent
property.
During the shot conducted on Thursday 9/8194 rock was thrown from the shot on the
fourth level. This shot consisted of two holes in a boulder, approximately 24 toe holes
to level the floor, and holes on the production beach above the toe holes.
The consensus is that the rock ejected from the pit came from the toe holes.
Apparently one of the toe holes was located close to an area of incompetent or
prellrartured material.
Upon detonation the explosive energy found the path of least resistance out through
the incompetent or pre -fractured material causing the rock to be thrown from the pit
onto the neighboring property.
The following recommendations are designed to give sufficient control to confine the
rock being blasted to the normal scatter zone within the quarry.
First; any toe holes to be shot should be covered with screenings to a depth that will
control the upward movement of the rock When detonated. This would address the
24 condition where a hole might be too close to the edge of solid rock next to
incompetent or prefractured material, as in the case of leveling holes in the floor
whe' re it is difficult to see where the solid rock ends.
Second; develop and use a method to log all blast -holes drilled. This drill log should
show the amount of fractured material plus any anomalies encountered during
drilling, such as cracks, soft searn_s, mud seams, cavities, etc.

��a ice. aJ y.�u JI1 'tuuJ oiLi+ LV L 1L'LAN 1% 111 -- yaa 01%l1Ull
The ability of a field blaster can be tremendously improved with the use of proper
and accurate drill logs. These drill logs can show where the fractured material is
located and gives him the ability to design the load according to the integrity of the
rock structure encountered by the drill string.
Third; consideration should be given to possibly getting setup to video shots. This
can be a very useful tool for blasting.
When reviewed in slow motion it can show such things as gas venting, indicating a
crack or seam that may not be evident in a visual inspection of the face_ It can also
show where movement may be restricted causing improper relief in subsequent rows.
It may show where oversize material is generated within the shot
Reviewing all of these could help improve future blasts by helping pinpoint areas of
concern so adjustments can be made for conditions shown in the video.
The above listed recommendations will improve control of scatter of blasted rock
Sincerely,
Z/-,/

Jim:
Attached please find three delay patterns representing your previous and current patterns along
with a proposed pattern. The previous pattern represents your timing used before experiencing
your current toe problem resulting from your current pattern.
Your flyrock incident described by Mark Ostwalt could have been the result of a lack of relief
created by the toe left from the previous shot. The build up of a toe creates additional amount of
burden for the front row resulting in the energy being directed to an area of the face with more
relief (less burden) as well continuing to leave a toe for the next bench/face.
The attached patterns illustrate the angle of relief based on the surface nominals. As you can see
the proposed pattern matches the previous timing before the toe problems while maintaining the
simplicity of a dual component system (EZ Det ® ). Given your historical success with the 42ms
down the control row it is our recommendation that Teer return to the proposed pattern.
If you have any questions concerning the proposal please contact me at 203-843-2029.
Best Regards,

Re: Flyrock Incident at Teer Company's Rocky Mount Quarry
Permit No. 33-13, Edgecombe County, NC
Dear Mr. Davis:
As you are aware, our Rocky Mount Quarry experienced a flyrock incident at 4:59 pm
on Thursday, September S, 1994. Your office was notified by FAX on Friday, September 9,
1994. The shot consisted of thirty six (36) production holes and twenty (20) holes drilled in a
toe just to the left and at the base of the wall. The production holes were drilled on 7' x 10'
burden to spacing pattern and were 30' to 32' in depth. The toe was drilled on a 6' x 6' burden
to spacing pattern and were 6' deep. In addition, a large boulder was also shot during the same
initiation sequence to crack it. I
The shot was loaded with 5,0261bs. of explosives consisting of 3,550 lbs. of ANFO, 936
lbs. of wet hole explosives (3 x 13 AP), 440 lbs. of bottom primer (Apex 3-1/4 x 16), 64 lbs.
of top primer (2 x 8), and 36- 1 lb. boosters. The production shot averaged twelve foot (12')
of stemming on the front line of holes and six foot (6') on the back lines. Of the total poundage
of explosives, 170 lbs. was consumed in the toe shot. The holes in the production shot were
initiated using a redundant non -electric system. The toe shot was initiated with electrical caps
with sufficiently spaced timing so that a maximum of 34 lbs. of explosives were being initiated
per delay in the toe shot. The production shot contained approximately 140 lbs. of explosives
per delay. The closest off -site occupied dwelling is approximately 1200 feet from the shot
(Winstead residence) where the flyrock landed and where the seismograph was monitoring.
Mr. Jerry Bass, Teer Company's Pit Foreman, supervised the loading of the shot and was
responsible for wiring it in, or in the case of non -electric, making the appropriate connections.
He also set up the seismograph at the Winstead house to monitor and record the peak particle
velocity and air Mast generated by the shot. When the shot was initiated, Jerry observed flyrock
landing on the Winstead. property. On Friday morning, September 9, I was notified of the
incident by Mr. Clarence Bolling, our Rocky Mount superintendent. At that time, 1 dispatched

Steve Edgerton to the site to investigate the incident and to notify your office of the problem.
Vibra Tech was also notified at this time and was requested to perform an evaluation of the
incident on Monday, September 12.
As a result of the investigation on September 9, 1994, it appeared that there was some
minor damage to the Winstead property as a result of the flyrock. This damage included
knocking a couple of two inch tree Iimbs out of a pine tree in the front yard of the Winstead
residence. Subsequent investigation on September 10, 1994, by the Winsteads, revealed that a
rock had knocked a hole in a wash tub hanging on the Winstead storage shed and into the wall
of the shed behind the wash tub. Repairs have been initiated at the Winstead property and
should be completed within the week. In conversations with Mr. Winstead it is apparent that
he is not aware of any other damage as a result of this incident.
The Winsteads have complained in the past about structural cracks in the brick veneer
on their house, cracks in concrete slabs and various other items. These complaints have been
investigated in the past years and it has been determined that they are a result of settling
foundations and not from the blasting operations conducted tat Rocky Mount Quarry. As a part
of Rocky Mount Quarry's blasting program, the Winsteads are called prior to the blasts so that
they will not be surprised by the vibration or the air blast. Pursuant to the Winsteads' wishes,
we will continue to contact them via telephone. In addition to this, all shots are monitored at
the Winstead residence with a representative of Teer Co. going to the residence to set up the
seismograph and monitoring the shot. Should the Winsteads be outside of the house and away
from the phone, but in the yard where the Teer representative monitoring the shot can see them,
we notify the Winsteads in person of the upcoming shot. i
Teer has always had a good working relationship with the Winsteads and we appreciate
their patience and understanding. Teer will continue to do everything in their power to see that
incidents such as this do not happen again.
On Monday, September 12, ICI Explosives and the Ensign - Bickford Co. were asked
to investigate what cause(s) led to the occurrence of flyrock from this particular shot. Their
individual reports are included in this report to your office.
From what has been ascertained, it is evident that the toe portion of the shot
generated the flyrock that hit the Winstead property. One of the holes in the toe may have
been adjacent to some loose or highly fractured material. Upon detonation, some of the
explosive force followed the path of least resistance, causing some of this loose material to be
thrown from the pit and onto the Winstead property. An aggravating factor was that the toe
holes were the First holes to be initiated in the blast sequence. This precluded the production
shots from having a dampening, or blanketing, effect on the 'toe holes. If the production holes
had been initiated a few milliseconds before the toe holes were fired, a blanket effect could have

been realized.
There are several factors which substantiate the theory that the toe shot caused the
flyrock. The first of which is the vibra-tech shot analysis report prepared by Jay Rodgers of
Vibra Tech. A close examination of this report reveals that the air blast was 138dba which is
not in compliance with the permit and is louder than a normal shot for this site. Air blast is
typically caused by a loss of explosive energy to the atmosphere. This can be a result of joints,
fractures, voids, reduced burden, cracks or insufficient stemming of the blast holes. The rock
typically absorbs this energy when it is being broken apart thus dampening the air blast. Should
there be an insufficient amount of rock to absorb the energy the force of the blast will escape
into the atmosphere causing an excessively high air over pressure reading or air blast. In
conversations with the foreman, driller and superintendent, it does not appear that any unusual
factors such as those listed above were encountered in the production shot which would have
caused the high air blast readings and flyrock. If a lack of stemming had been the cause of the
air blast and flyrock it would have manifested itself visually by creating what is known as a
"blow-out", which looks like a column of smoke or dust rising vertically from the shot. This
occurs when there is insufficient stemming in the hole to contain the blast energy and the energy
producing gases escape through the opening of the blast -hole. This also will create flyrock and
excessive air blast. Mr. Bolling, the site manager, witnessed the shot and stated that he did not
observe any blow -outs in the shot. Therefore, if no blowouts were observed in the shot and no
unusual cracks, fractures, or voids were encountered while drilling the shot, it stands to reason
that there must have been reduced burden, evidently in the toe, which allowed the explosive
energy to escape. As mentioned earlier, if the holes for the toe shot were drilled near fractured
material this would result in reduced burden which would allow the explosive energy to escape
creating air blast and flyrock.
Another factor which supports the conclusion that the flyrock was generated from the toe
shot is the distance calculation based on the seismic monitoring data. From the calculations
generated by Jay Rodgers of Vibra Tech it appears that the source of the air -blast was
approximately 1200' from the seismograph and the seismograph was located in the incident area.
Since air blast and flyrock often are associated with each other it is reasonable to assume that
they both originated in the same area. This distance, when measured off of the plans, correlates
well with the location of the toe shot.
At the same time the production and toe shots were initiated, a boulder shot was also
initiated. While the boulder shot was initially considered as the source of the air -blast and
flyrock, its location and condition after the shot indicated that this was not the source. The
boulder was located some 1400' from the shot which does' not match the calculation of where
the source of the air -blast was. The boulder shot was designed to simply split the boulder into
and from its appearance after the shot it appears that this is'what occurred, with very little loss

of material, (ie. it appears that the boulder was sliced into with a knife and not pulverized).
While examining the boulder note was made of any fractures joints or possible planes of
weakness which could have contributed to the incident and none were observed. Based on these
observations and calculations the boulder shot was eliminated as a possible cause.
Scaled distance calculations based on the lbs/delaylof explosive and the distance to the
nearest occupied dwelling, the Winstead residence, were performed to ensure compliance with
standard safe blasting practices. Based on these calculations the production shot had a scaled
distance of 101.42 and the toe shot had a scaled distance of 205.80. Even if two of the
production holes overlapped and went off at the same time, due to cap scatter, the scaled
distance would still yield 71.7. The industry standard for a safe shot is a scaled distance of 50
while Teer Co. typically tries to have a scaled distance of no less than 60. Even in a worst case
scenario it appears that the shot was conservatively loaded to reduce ground vibration felt by
neighbors. The higher the scaled distance the lower the amount of energy available to vibrate
a structure, thereby reducing the ground vibration at the structure.
A review of the blast diagram and the delay patterniifor both the production and the toe
shot does not reveal any deviation from other shots which might explain why the incident
occurred. A review of the timing for the shot does not reveal an opportunity for any excessive
amount of cap overlap which would result in more than one hole shooting at one time. The
production shot pattern is essentially the same as the pattern which has always been used a 7'
burden and 10' spacing.
I
Based on the above information Teer, Vibra Tech and ICI explosives have all concluded
that the toe shot was the source of the air blast and the flyroek. With this information, Teer and
its consultants have developed some recommendations which are being tendered for your review.
These recommendations will be implemented immediately upon your review and approval for
the resumption of blasting operations at Teer's Rocky Mount facility.
Since the flyrock incident that occurred in November 1, 1993, which was the result of
a "cutoff" in a majority of the production holes in one shot, it was decided to go to a redundant,
non -electric detonating system to prevent a similar situation from occurring again. At that time,
the only redundant system available was one that employed `a 25 millisecond surface delay and
a 475-500 millisecond down hole delay. However, since going to this system, we have
experienced an increased amount of toe problems as a result of production blasting with this
delay pattern. It appears that the 475 to 500 millisecond down hole delay to light the entire shot
is too long a time period. We have found that delays in excess of 375 milliseconds are
inaccurate from a timing standpoijnt. Also, we feel that the 25 millisecond delay (surface)
between holes is to short a period of time to minimize the creation of toes.
Since "shooting" toes are less predictable than production shots, it is desirable to minimize the
potential for creating toes at the outset. Another manufacturer of blasting caps

which incorporates a redundant system has recently come out with different delays which are
closer to the delay system previously used at this site. Since the delay pattern used prior to the
November 1, 1993, incident did not yield toe problems, it is recommended that Rocky Mt. go
back to the earlier delay pattern with a redundant system ,'since these delays are now available
in a redundant system. This should lessen the likelihood of developing toe problems as well as
incorporating a redundant system into the shot which will lessen the likelihood of having a cutoff
on the shot.
In the event that toes are encountered in the future the following procedures will be
conducted to lessen the possibility of the toe shot producing flyrock and excessive air blast:
Once the shot is loaded and connected a blanket of screenings a minimum of 3'
thick will be carefully placed on the toe shot Ito buffer the shot. This blanket will
extend a minimum of one hole spacing in all directions around the loaded holes.
This should effectively reduce the chance of any materials being thrown from the
shot because one hole was drilled next to fractured material with insufficient
burden. The thickness of the blanket is not an arbitrary number. Included in the
appendix of this report is an analysis and chart which will aid the operation in
determining the amount of cover to be used Ion toe shots.
The driller will keep written logs of all holes drilled for toe shots, making note
of any incompetent rock. The foreman will`be made aware of these conditions
and no holes will be loaded in less than competent material. Holes will be drilled
on the same pattern and spacing around the outside of the toe shot to ensure that
there is competent material around the toe. If during this drilling process
fractured or broken materials are encountered the blast holes in the toe shot will
be appropriately reduced. This should reduce the chance that a hole will be
Ioaded which is next to fractured or broken materials. All holes which are drilled
outside of the toe shot will be immediately backfilled with drill cuttings to ensure
that they are not accidently loaded.
The timing of all future blasts will be designed so that the production shot will
be initiated prior to the toe shot. As discussed earlier this will create a situation
in which the production shot will act as an' additional blanket to reduce the
possibility of flyrock leaving the blast area. j
Rocky Mount will undertake actions to reorient its blasting so that any materials
which may inadvertently become airborne will not travel in the direction of the
Winstead residence but in the direction of the plant stockpile and pond area. This
reorientation of the shots will take some time because of the pit benches and their
present orientation, This will be accomplished over time and will add a greater

safety factor to the blasting program at Roc` y Mount.
CONCLUSION:
Teer has actively investigated the flyrock incident of September 8, 1994, and feels that
the cause of the incident was the toe shot. Once the cause of the incident was determined a
thorough investigation into what could be done to alleviate the cause in future blasting operations
was performed. Teer feels that the above outlined procedures should eliminate flyrock
associated with toe shots. As always, Teer is actively striving to institute the safest possible
blasting techniques into its operations.
As you are aware Rocky Mount Quarry is presently, unable to shoot until you and your
staff have reviewed and approved the above report. Your prompt review of this report would
be greatly appreciated since we are presently in the peak of our production season. Teer also
realizes that a thorough examination of the data is needed to properly assess if all of the issues
have been adequately addressed. If you or your staff should have any questions please do not
hesitate to call me at 919-380-2612. '

Flyrock incident notification
Dear Mr. Davis:
On Thursday September 8, 1994 at 4 : 59 pm Teer Cos. Rocky Mt. Quarry
experienced a flyrock incident. Approximately 3 to 4 fist sized
pieces of rock from the quarry travelled 1200' and landed in Mr.
Greg Winsteads yard. Mr. Winstead owns the adjoining property
across highway 97. There was no injury sustained nor any serious
property damage. A 1" diameter pine tree limb was broken out of
the tree and some small divots were made in Mr. Winsteads lawn.
From the preliminary investigation that I have conducted it appears
that a hole blew out while shooting a toe shot next to the face of
a main shot. The Air Blast reading for this event was 136 dba
which would indicate that the hole did indeed blow out.
No further blasting will be done at the site until a complete
investigation has been conducted of the incident and your office
has reviewed the findings of the investigation and notified Teer to
again commence blasting operations.
Mid -Atlantic Explosives and vibra-Tech Engineers will be on site
Monday September 12, 1994 to aid in the investigation and prepare
a report of the causes and the solution to the problem. It is
anticipated that a complete report with causes and solutions will
be prepared for your review by Wednesday September 1.4, 1994.
I will keep you updated as the investigation progresses. Should
you have further questions please do not hesitate to call me at
919-380-2615 wk. or at home 919-847-6153.

Re: Flyrock Incident at Teer Company's Rocky Mount Quarry
Permit No. 33-13, Edgecombe County, NC
Dear Mr. Davis:
In the course of conducting normal operations at Teer
Company's Rocky Mount Quarry, a shot was initiated on November 1,
1993 at approximately 3:00 pm. The shot consisted of 43 holes, 30'
to 35' deep, on an 8' x 10' burden to spacing pattern. The shot
was loaded with 8,025 lbs. of bulk anfo explosives and was
initiated with a non -electric detonation system. Jerry Bass, Teer
Company's Pit Foreman for this facility, supervised the loading of
the shot and personally wired up the shot. Mr. George Erwin, a
blasting supervisor for ICI Explosives, was present at the site and
was in agreement with Jerry that the shot was properly loaded and
wired.
Jerry set up the seismograph at the Winstead house to measure
ground vibration and air blast. After the shot was detonated and
upon inspection of the shot, it was discovered that the shot had
suffered what is known as a "cut off". A cut off occurs when the
circuit which interconnects the holes is disrupted and initiation
of the entire shot is interrupted. In a non -electric initiation
system, this can occur in the following ways:
1) A rock can cut the interconnecting tubing between holes which
will stop shot detonation in the hole preceding the cutoff.
2) The connecting tubing between the holes can be stretched out
of the connectors as the shot moves out after detonation.
3) Malfunctioning caps which do not detonate.
4) An improperly designed or wired shot.

Upon inspection of the partially detonated shot, it was
decided that in areas where the shot had detonated and the holes
left behind had a reduced burden that water would be poured down
the reduced burden holes to decrease the amount of explosive in
these holes. By pouring water into a hole filled with anfo, the
water will dissolve the anfo, thus reducing the amount of explosive
contained in the hole. This was done for all holes, except one,
behind the row which detonated. This one hole was extremely wet
and an emulsified anfo was used, which protects the explosive from
the water. Therefore, there was no safe way to remove this
explosive from the hole. The holes which had reduced explosives
were re -stemmed to ensure reduced air blast.
Upon completion of the above operations, the shot was rewired
and readied for initiation upon final inspection of all connections
wiring and overall shot conditions. Jerry set up the seismograph
at the Winstead's house and the shot was detonated while Jerry was
at the house with the seismograph. While Jerry was noting
seismograph readings and packing up the machine, Mrs. Winstead's
daughter (who lives within 200' of the Winstead's house) came over
and spoke with Jerry about how loud this particular shot was.
Jerry explained there had been a problem with the shot and that
this was not a normal occurrence. The daughter also mentioned that
she thought she had heard something, but when Jerry offered to
accompany her to investigate the sound, the daughter declined.
On November 2, 1993, Mrs. Winstead informed the Rocky Mount
operation that a rock had penetrated the roof of her shed and
damaged a shower stall stored in the shed. Upon completion of an
investigation into the complaint, Rocky Mount personnel immediately
notified me and I notified Beth Chesson with the NC DEHNR, Land
Quality Section.
Mrs. Winstead's shed roof

was immediately repaired and
made for the replacement of the

The rock in question was approximately six inches (611) in
diameter and traveled approximately 1,600 linear feet. Jerry Bass,
who was near the scene when the incident occurred, did not see the
rock nor was he aware of any damage until notified by Mrs.
Winstead.

Mr. Tracy Davis
Page 3
After reviewing available information, the cause of the
incident appears to be three fold. First, a shutoff occurred in
the shot after nine holes detonated, leaving reduced burden in a
portion of the shot. Second, one hole which was in the reduced
burden area was filled with emulsion and the amount of explosives
contained in this hole could not be safely reduced via traditional
methods. Third, due to a partially detonated shot, the timing of
the shot was thrown off, possibly redirecting blast energies
creating different throw directions of the material.
After a review of the incident, the best solution would be to
place additional materials against the new faces of the shot
created by the cutoff. This will, in effect, increase the burden
of the exposed faces and reduce the chance of flyrock.. The
�[ material will be placed from the bottom up so that no equipment
will be operated on a live shot, thus complying with all safety
regulations. This practice will be initiated within Teer Company
from this point forward.
Another practice which Teer Company is presently investigating
is the use of redundant lines to tie shots together. A performance
analysis is presently being performed at Teer's North Durham
Quarry, and should results of this system be satisfactory, we would
switch our operations to this system. Basically, each cap has two
initiation tubes per cap instead of one. These caps are wired in
such a manner so that if one line is severed, the cap can still be
initiated with the other line. This would greatly reduce the
chance of cutoffs within the initiation system.
Also included for your review are blast diagrams of this shot,
blast reports, seismograph reports, accident investigation report,
shot reports from two previous shots, peak particle velocity
reports, and seismograph data for November 1. shots and for all
shots in October.
Since notification of the state of the flyrock incident, no
blasting has occurred at the site nor will any blasting occur until
notified by the Land Quality Section that Teer may proceed with
normal operations.

From a Omrao Irwi �tr -
Dear Steve,
This letter is concerning the production shot at Rocky Mount Quarry on
11-1-93. I was assisting Jerry aa4s in the loading of bulk material on this
shot .
The boreholes were loaded with a 4' to 5' base charge of Poweran
5OOO.'The remainder of the borehole was loaded with bulk anfo. Borehole&
were then stemmed to the proper depths. After completion of loading.
Jerry began to hook up the surface unite. I proceeded to the top level were
I would be able to observe the blast when fired.
When the beast was fired I noticed the only row to fire was the first row.
Aher the propel' amount of time, (approx.13 minutes) we returned to the
shot ^roa where we found two surface delays that had not fired. It was
unclear what the cruse of the shutdown was at that time.
We there proceeded to flush the two time holes that were exposed with
water and restern the hales. Sorry hooked the shot up again and retired the
shot. I did notice that one of the holes blew out but did not detect any
material leaving the pit area. The next afternoon, I learned that a flyrock
situation had occurred. I feel we did everything we could to prevent a
flyrock situation,
