Appendix E: Coal Mining and Processing Methods Coal

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

Beam Stage Loader and Crusher underground COAL

Equipment Beam Stage Loader and Crusher. When the coal has been hauled to the maingate, it then has to be transferred through a 90 o turn, and loaded onto the maingate conveyor. This function is carried out by the "Beam Stage Loader or BSL", which is another scraper conveyor, in this case with steel plates on both sides and runs from the maingate drive to the maingate conveyor (belt).
