Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.

In surface mining, the ground covering the coal seam the overburden is first removed to expose the coal seam for extraction. The elements of a surface mining operation are 1 topsoil removal and storage for later use, 2 drilling and blasting the strata overlying the coal seam, 3 loading and transporting this fragmented overburden material called spoil , 4 drilling and blasting the
After coal is mined, it needs to be transported to and conveyed through a processing plant to prepare it for shipment and sale. McLanahan’s line of Feeders can move coal from one aspect of the processing plant to another. They feed material at a rate that matches the capacity of a crusher or conveyor belt.
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.
