Chapter II
There are two storage areas, one for B-bed raw coal, the other for M-bed raw coal.
• The coal from each seam is kept strictly segregated. Presently the coal is stored in
open stockpiles. However, the raw coal will be stored in underground bunkers with
the continuation of our modernization program.
Coal is "reclaimed" from the stockpiles to conveyor belts which run through buried
12' steel pipes. The belts convey the raw coal to storage bins. belt to the wash
plant.
The coal is carried, again on covered conveyor belts, from the raw coal storage
bins to the preparation plant.
At the preparation plant, rock and refuse materials are removed from the coal by
gravity separation methods and froth floatation. After cleaning, the coal is thermally
dried and placed in clean coal storage bins.
There are four clean coal bins. As throughout the process, in clean coal storage, the
coal from each of the two seams mined is strictly segregated.
The clean coal is measured, from the clean coal storage bins, onto a collection belt
which carries to the "blending bin." Ratio weigh feeders at the bottom of each clean
coal storage bin allow Mid-Continent to control the proportion of coal from either
seam which is loaded into the blending bin. In that way, customer specifications for
• coal from either or both seam can be met.
The blended coal is stored in a clean-coal bin, from which it's loaded onto trucks
which transport it to the load-out facility at Carbondale, approximately 23 miles
away.
At the load-out, the coal is transferred from the trucks to the train load-out storage
bins, and in turn carried to the train loading tipple on belt conveyors. From the
tipple, it's loaded on the trains.
The rock and other impurities separated from the salable coal is transported from
the wash plant to the refuse disposal area on a conveyor belt, which is also covered
for dust control. This belt also is turned after the coal is unloaded to the refuse pile,
so as to prevent coal particles from falling on the ground beneath the conveyor.
b. Mine Entries #3, #4, #5.
To complete work on the Adit/Rock Tunnel lateral extensions must be made to the
workings of Entries #3,#4 and #5. At the time of permit submittal, (December,
1987) these are inactive, due to constrained demand for coal.
