Continuous mining Article about continuous mining . Over the past few months the mine has commenced an operational transition from continuous mining (using a machine with a large rotating steel drum equipped with tungsten carbide teeth), which was not economically viable due to prevailing geological conditions, to long wall mining (in which a long wall of coal is mined in a single slice).
