A form of surface mining in which bulldozers, power shovels, or stripping wheels remove the overburden in strips. It is used in areas with fairly flat terrain. An earthmover strips the overburden and then a power shovel digs a cut to remove the mineral deposit. It is typically used for coal and some phosphate rock.

Coal mining and the environment. The primary impacts arise from mining, particularly underground mining, largely because South African coal mines are relatively shallow. Coal washing gives rises to large waste dumps, which may ignite spontaneously and cause air pollution. Water pollution arises from some abandoned mines and waste dumps.

Origin, Composition, and Structure of Coal. Inorganic compounds such as aluminum and silicon oxides constitute the ash. Distillation produced tar, water, and gases. Hydrogen was the chief component of the gases liberated, although ammonia, carbon monoxide and dioxide gases, benzene and other hydrocarbon vapors were present.

Coal Mining in South Africa. Coal mining's advent in South Africa can best be traced to the start of gold mining in the late 19 th century, particularly on the Witwatersrand, with the first coal in appreciable tonnages being extracted on the Highveld coal field close to the nascent Witwatersrand gold mines. However, demand began to grow, slowly at first but then exponentially as the country entered a period .
