Saziot - 2.05.3
headhouse on top of Slacking Tube No. 1. A transfer point at the beginning of the elevated section
will allow coal refuse or mine development waste to be diverted through a discharge chute to a
temporary st«kpile. The conveyor will have a capacity consistent with the design annual production
rate. The conveyer is constructed with steel supports on concrete foundations and includes partial
covers for dust control, walkways for inspection and rrtaintenance, and emergency stop controk in
compliance with applicable MSHA safety regulations.
Coal Storage Areas -There are two areas where coal could presently be stockpiled; 1) The East Yatd
coal st«kpile; and 2) The Ells Geek coal st«kpile. Coal st«kpiled in these azeas includes coal
dehvered to the facilities area from other mines in the area and coal mined from the Sanbom Creek
and Ells Geek Mmes.
The East Yazd coal st«kpile area receives coal primarily from the Sanbom Geek Mine, however, coal
may also be hauled to this st«kpile from other mines in the area. Coal is diverted off the Sanbom
Creek Mme overland conveyor belt through a transfer point and discharge chute to a stacking belt
which delivers the coal to the stockpile azea. The East Yatd coal stockpile has a capacity of up to
30,000 tons of coal. Coal is recovered from this stockpile by wheel loader and loaded into trucks to
be hauled either off-site or to the on-site dump station. The East Yard st«kpile and coal handling
system can also be used for handling and temporary stockpiling of coal refuse or mine development
waste.
The Elk Geek coal st«kpde was originally an open st«kpile with a capacity of approximately 60,000
tons. In conjunction with the mine expansion initiated in 1995, this st«kpile was modified to add
two stacking rubes, an ass«iated coal distribution system, and asub-grade coal reclaim system and to
expand total st«kpile capacity to approximately 300,000 tons. The two coal stacking rubes erected in
the expanded Elk Geek coal st«kpile area are reinforced concrete rubes mounted on reinforced
concrete foundations. The rubes have openings in the sides and flexible covers to allow the coal to
discharge from the rubes to create conical coal st«kpiles.
The Stacking Tube No. 1 Headhouse contains a tripper, diversion gates, and chutes to allow the coal
to discharge to either Tube No. 1 or to a transfer conveyor rotating to Stacking Tube No. 2. In
addition, the Stacking Tube No. 1 Headhouse u designed and the ass«iated systetrts configured to
accomnwdate tie-in of the feed conveyor from the Elk Geek Mme to the north. All conveyors
include partial covers for dust control, walkways, and emergency stop controk for inspection and
maintenance and in compliance with applicable MSHA safety regulatioru and coal transfer points will
be partiallyor fullyenclosed for dust control.
The expanded Elk Geek st«kpile area is graded to accommodate both the live storage ass«iated
with the two stacking rubes and dead storage. Sideslope areas along the east and west margins of the
st«kpile were cleared, grubbed, and available topsoil removed to accommodate additional dead
storage. Under normal operating conditions, the designed live storage should be adequate to support
normal mine production and loadout operations. Prior to any extended mine shut-down such as
when the longwall must be rel«ated to a new panel, however, doors will be used to push coal
outward from the stacking tubes to take advantage of additional dead storage capacity so that the
st«kpiled coal can be utilized to maintain normally scheduled loadout operations until normal mine
production can resume.
The st«kpile reclaim system recovers coal from the live storage ponion of the expanded Elk Creek
coal st«kpile and transfers it to the new coal screening installation. The reclaim system consists of a
reinforced concrete box tunnel under the coal st«kpde with multiple drawpoinu and vibratory
feeders which draw coal from the base of the coal st«kpile and discharge to a transfer conveyor.
• The concrete tunnel extends cleaz under the coal st«kpile and includes an emergency escapeway,
walkways, lighting, ventilation, drainage sumps, and emergency stop controk for inspection and
maintenance m compliance with applicable MSHA safety regulations.
