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 year 1556, dolioform ROM Jigging Bath was used for mineral processing, since early 1800s it was applied into coal washing, and in 1950s, it spreaded all over coal mines in middle Europe. In year 1820, German professor Dr. Hartz developed ROM Jig to fixed screen piston jig, and it was used for minrral processing by pulsating water flow, in ...
