    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

    The surface mining methods are: (i) open pit mining, (ii) drift mining, (iii) slope mining, (iv) contour mining, and (v) auger mining. The characteristic that distinguishes open pit mining is the thickness of the coal seam insofar as it is virtually impossible to backfill the immediate mined out area with the original overburden when extremely

    In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use (Figure 11). With underground mining, in contrast, a series of openings is made from the surface to the
