Coal Mining Separation Process

  • 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
