    2020-5-8 · A continuous miner is a mining machine that produce a constant flow of ore from working face of mine. The machine continuously extracts as it is loading coal with continuous steel drum and conveyor system. Continuous miners can typically use in room and pillar mining operations. The continuous miner is different from conventional and cyclicalMining Coal Mines,Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner’s progress.
