The case of contour mining process

chapter 2 the environmental effects of strip mining theauger mining usually takes place in conjunction with a contour mining operation. once the contour operator reaches the point where the height of the highwall makes it uneconomical to remove further overburden, the operator may choose to extract further coal, before beginning reclamation, by drilling into the face of the highwall with a miningsurface mining strip, open pit, mountaintop removalsurface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. it is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. surface miningcoal mining choosing a mining method britannicacontour mining is commonly practiced where a coal seam outcrops in rolling or hilly terrain. the process is repeated in successive parallel cuts until the stripping ratio indicates that continued surface mining is uneconomical. openpit mining. in openpit miningwhat is strip mining?
