Jan 26, 2010· Raw coal is stored on the surface in the original 15,000-ton raw coal bin or a newer 40,000 ton stacker. The mine operates in the Pittsburgh seam and is the sole source of coal for the prep plant. All production is fully washed. Typical annual production for the last five years is 6.5 million tons of clean coal. Yield averages 80% to 82%.
After removing the coal from the ground, the miners may send it to a preparation plant near the mining site. The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials. This process increases the heating value of the coal.
