4 Coal Mining and Processing Coal: Research and

Coal Mining Coal seams can be mined by surface or underground methods (Figure 4.3), with the choice of mining method dictated by both technical and economic factors. The most important technical factors are the thickness of the coal seam, the depth of the coal seam, the inclination of the seam, and the surface topography.

Mining Process BNI Coal

Before mining begins, a rotary drill is used to define the lignite field, the depth and thickness of lignite seams, and the amount and type of material (or "overburden") overlying the lignite. This information is used by BNI engineers to determine where the best lignite deposits are located.

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
