    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

    Dec 04, 2019 Surface mining is done in five ways: Strip mining – Strip mining is the most common surface mining method used to mine coal and lignite. The process is done by removing a strip of overburden before mining a seam of mineral. Strip mining is done only when the ore body is in close proximity to the surface. Open-pit mining – Open-pit mining is
