Contour mining makes cuts on the slope where the coal seam is loed, to remove first the overburden and then the coal itself. Overburden from adjacent cuts is used to fill previous cuts. The operator continues making cuts until the ratio of overburden to coal becomes uneconomical. The operation then continues along the contour of the mountain until the coal resources, or the operator's ...
