Strip Mining. In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coal. The large intermediate layer of sediment and rock, i.e., the 'overburden' is then blasted and removed using large trucks. Once exposed, the underlying coal seam is excavated in strips and transported out ...

Hence, the coal ash content should be maintained reasonably constant preferably to within about +1- 2%. High ash coals, up to 35 or 40% ash content, can be used in cement kilns provided that the ash content is controlled. For coals above about 15% ash content a stockpile-reclaim blending system is usually required.
