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 …

in terms of plant yield. In most cases, a higher overall plant yield may be realised by producing the coarse and the small coal at slightly different product qualities4,5,6. The difference in liberation between the coarse and the small coal very often results in the small coal exhibiting better washability characteristics than the coarse coal.
