Petitions for Modification
The following parties have filed petitions to modify the
application of mandatory safety standards under section 101(c) of the
Federal Mine Safety and Health Act of 1977.
1. Keystone Coal Mining Corporation
[Docket No. M-95-86-C]
Keystone Coal Mining Corporation, 655 Church Street, Indiana,
Pennsylvania 15701 has filed a petition to modify the application of 30
CFR 75.380(d)(3) (escapeways; bituminous and lignite mines) to its
Emilie No. 1 Mine (I.D. No. 36-00821) located in Armstrong County,
Pennsylvania. The petitioner proposes to continue utilizing the
passable escapeway as it presently exists for approximately 8 to 9 feet
as an alternative to enhancing the height of the overcast area due to
geologic conditions of that area of the mine. The petitioner states
that the main intake escapeway (E1) for the Emilie No. 1 Mine is
directed out of the Emilie No. 2 Track Slope; that petitioner is unable
to maintain the clearance to the height of the coal seam at one corner
of the intake overcast located three crosscuts inby the slope bottom
due to geologic conditions; that the clearance at the immediate corner
of the overcast is 24 to 29 inches in height and that moving away from
the immediate corner towards the center of the overcast and down the
ramp, the height increases to 42 inches, which is the height of the
coal seam; and that the total linear distance is 9 feet where the
travelway is less than the seam height. The petitioner also states that
application of the standard would result in a diminution of safety to
the miners because a much greater distance would have to be traveled
along a different escape route. In addition, the petitioner asserts
that the proposed alternative method would provide at least the same
measure of protection as would the mandatory standard.
2. Keystone Coal Mining Corporation
[Docket No. M-95-87-C]
Keystone Coal Mining Corporation, 655 Church Street, Indiana,
Pennsylvania 15701 has filed a petition to modify the application of 30
CFR
[[Page 35236]]
75.380(d)(4) (escapeways; bituminous and lignite mines) to its Emilie
No. 1 Mine (I.D. No. 36-00821) located in Armstrong County,
Pennsylvania. The petitioner proposes to continue utilizing its
secondary/alternate escapeway as it presently exists. The petitioner
states that the secondary/alternate escapeway for the Emilie No. 1 Mine
is directed through to the East Mains Section cut through to the Emilie
No. 2 Mine's main line track entry, along the belt and track, and up
the belt slope to the surface; that two features in and about the slope
area of the escapeway are less than the requirements of the standard;
that the distance from the sidewall of the slope to the edge of the
belt is 54 inches wide and the two airlock doors in the slope are 46
inches wide. The petitioner states that application of the standard
would result in a diminution of safety to the miners because a much
greater distance would have to be traveled along a different escape
route. In addition, the petitioner asserts that the proposed
alternative method would provide at least the same measure of
protection as would the mandatory standard.
3. Canterbury Coal Company
[Docket No. M-95-88-C]
Canterbury Coal Company, R.D. 1, Box 119, Avonmore, Pennsylvania
15618 has filed a petition to modify the application of 30 CFR
75.380(d)(3) (escapeways; bituminous and lignite mines) to its David
Mine (I.D. No. 36-00813) located in Armstrong County, Pennsylvania. The
petitioner requests a modification of the standard to allow passage of
the alternate or secondary escapeway through an area where crossing
over two overcasts limits the passage height to less than 5 feet. The
petitioner states that the two overcasts were installed in the mine
prior to 1971; that the secondary or alternate escapeway is routed over
the overcasts which isolate it from the belt and track entries; that
the height of the secondary escapeway over the overcasts is 42 inches
for 12 feet, and 43 inches for 13 feet at the track and belt overcasts;
and that all personnel entering the mine are instructed on escapeway
and escape procedures. The petitioner asserts that the proposed
alternative method would provide the safest and shortest practical
means of escape from the active mining section.
4. R. S. Coal Company
[Docket No. M-95-89-C]
R. S. Coal Company, P.O. Box 526, Trevorton, Pennsylvania 17881 has
filed a petition to modify the application of 30 CFR 75.1400 (hoisting
equipment; general) to its No. 1 Slope (I.D. No. 36-07108) located in
Northumberland County, Pennsylvania. The petitioner proposes to use a
slope conveyance (gunboat) in transporting persons without installing
safety catches or other no less effective devices but instead use an
increased rope strength/safety factor and secondary safety rope
connection in place of such devices. The petitioner asserts that the
proposed alternative method would provide at least the same measure of
protection as would the mandatory standard.
5. Primrose Coal Company
[Docket No. M-95-90-C]
Primrose Coal Company, 214 Vaux Avenue, Tremont, Pennsylvania 17981
has filed a petition to modify the application of 30 CFR 75.1002-1
(location of other electric equipment; requirements for permissibility)
to its Primrose Slope (I.D. No. 36-04629) located in Schuylkill County,
Pennsylvania. The petitioner proposes to use nonpermissible electric
equipment within 150 feet of the pillar line and to suspend equipment
operation anytime methane concentration at the equipment reaches 0.5
percent, either during operation or during a pre-shift examination. The
petitioner asserts that the proposed alternative method would provide
at least the same measure of protection as would the mandatory
standard.
6. R & D Coal Company
[Docket No. M-95-91-C]
R & D Coal Company, 214 Vaux Avenue, Tremont, Pennsylvania 17981
has filed a petition to modify the application of 30 CFR 75.1002-1
(location of other electric equipment; requirements for permissibility)
to its Buck Mountain Slope (I.D. No. 36-02053) located in Schuylkill
County, Pennsylvania. The petitioner proposes to use nonpermissible
electric equipment within 150 feet of the pillar line and to suspend
equipment operation anytime methane concentration at the equipment
reaches 0.5 percent, either during operation or during a pre-shift
examination. The petitioner asserts that the proposed alternative
method would provide at least the same measure of protection as would
the mandatory standard.
7. Cobre Mining Company
[Docket No. M-95-09-M]
Cobre Mining Company, 303 Fierro Road, PO Box 424, Hanover, New
Mexico 88041 has filed a petition to modify the application of 30 CFR
57.11055 (inclined escapeways) to its Continental Mine (I.D. No. 29-
00233) located in Grant County, New Mexico. The petitioner proposes to
modify the use of its present underground secondary escape route. The
petitioner proposes to install two vent or fire doors on the 1300 level
at the No. 2 shaft, one on each side of the shaft in the drifts leading
to and from the shaft; to have a rest or refuge station equipped with
telephone and audio, compressed air and water lines, suitable hand
tools, and stopping materials located between the air doors; to install
a ladderway in the No. 2 shaft cage compartments that would extend from
the 1300 level up to the 400 level station, a total distance of 900
vertical feet; to establish rest areas on the 1000, 800, and 600 foot
levels; to have a walkway approximately 450 feet from the 400 level
station that extends to the west wall of the open pit and daylight and
the 6-13 stope connected to the east end of the west wall of the pit;
to have the 99 stope connected to the bottom level of the pit and if
any changes are detected in mine ventilation, the emergency escape
would be carried out entirely in fresh air. The petitioner also
proposes to retimber all refuge stations, level stations, rest areas or
walkways, or install ground support when necessary; to remove all scrap
from the station area; to seal and lock all walkways (drifts) leading
from the rest stations into any unnecessary or abandoned stope areas.
After the ladderway from 1300 to 400 level is completed in the No. 2
shaft, the lagging would be removed from No. 53 for 316 feet and a
bulkhead would be installed, a concrete and rebar plug poured to form a
bearing set with a chute type drawpoint, the No. 2 shaft would be
filled with clean gravel from the concrete plug to the surface, the
manway would be constructed with 6 by 8 inch stringers nailed in from
the end plate to the center dividers, and 3 by 5 inch lagging would be
nailed down on the stringers to the outside of the shaft guides forming
a 48 by 51 inch landing with at least a 25 by 25 inch ladder opening;
at each landing 2 by 12 inch laggings would be installed from guide to
guide to form a horizontal partition, three laggings would be nailed on
a 1 foot space to a height of 5 feet, a chain link wire would be
installed between the landings to further close the manway, ladders
would be installed in 24 foot sections that would be inclined from each
landing to the center divider above and bolted to a 7 foot vertical
center divider for additional handholds. The petitioner states that no
electrical power would be near the
[[Page 35237]]
manway; that escaping miners would be in fresh air entirely from all
areas on the 1300 level; and that its approximately 3,300 feet from the
No. 3 shaft areas down 13-1 drift to the No. 2 shaft station and
approximately 4,800 feet from 13-17 drift off 13-5 drift to the No. 2
shaft station by 13-17 drift. The petitioner asserts that the proposed
alternative method would provide at least the same measure of
protection as would the mandatory standard.
