Contour Strip Mining
What is Contour Strip Mining? Definition and Overview. Contour strip mining is a method of surface mining used to extract coal that follows the contours along a hill or mountain side. Unlike traditional strip mining that removes vast and flat layers of soil and rock to reach coal seams, contour mining adapts to the landscape's natural curves.

Percussion and rotary-percussion drilling are used in non-coring drilling operations for medium to hard rock; applications include exploration and blasting boreholes, and degassing shafts. This type of drilling is used when a core is not needed for analysis. In percussion drilling, the main
Mine Tailings Disposal Methods
Extraction of the coal may continue by auger mining methods. Generally, the undisturbed overburden then collapses into the empty auger holes, and some surface subsidence may occur. Prior to strict regulations, disposal of overburden during contour mining consisted of leaving the spoil scattered over the natural slope below the cut.
