Appendix E Coal Mining and Processing Methods

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
