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.Influence of coal mining on the lower Yellow River region and related management countermeasures-- Taking Heze mining area as an example August 2022 …
