Technical Revision to Mine Plan to Include a Temporary Coal Washing
Plant and Waste Disposal Area
Dear Jim:
As you know, the Fruita No. 2 Mine is mining lump and stoker coal from the anchor
coal seam. At present the seam contains a rock split; in order to mine lump coal
of sellable quality, the lower portion of the seam is being mined by a continuous
miner producing stoker mixed with rock; the upper portion is being mined by a
cutting machine producing lump coal.
The stoker coal and rock mix is being stockpiled as permitted by a previous
Technical Revision. It has become apparent that the area for storage of the
stoker and rock mix will not be sufficient. It is imperative that installation
of the coal washing plant and waste disposal area be approved in order to keep
the mine operating.
Map FM-1 shows the locations of the washing plant and waste disposal area, along
with cross sections, waste storage volumes, topsoil ("A" & "B") volumes and
rock drain data. A flow sheet of the coal washing plant is also enclosed (see
figure 1). It should be noted that the washing plant is not permanent, as it will
be on a steel frame and not on concrete.
All construction will be within the permit area and the sediment control system.
Water Quality and Air Quality Permits have been obtained for the washing plant
and waste disposal area.
OPERATIONS PLAN
The washing plant (heavy media washer) will receive water from a 12,000 gallon
storage tank located directly east of the washing plant. The tank is not planned
to be buried. All water used by the plant will be recycled, less what is lost
on the reject and product coal. Product coal will be stockpiled until shipping.
The reject (see analyses) will be disposed of in the waste disposal area. Engi-
neering design of the waste disposal area is certified by Andrew Porter of
Geotechnical Engineering and Materials Testing.
