03/04/2017 Coal Mining is the term that encompasses the physical extraction or removal of coal from the Earth’s Surface. When coal is used as fuel in power generation, it is referred to as Steaming or Thermal coal while those which are used to create coke for steel manufacturing is referred to as Coking or Metallurgical Coal. Coal can be mined by both Surface and Underground Mining
Coal Mining Method.ppt Methods of Mining Mining Methods
Underground Mining Room and Pillar mining, the most common type of underground coal mining, coal seams are mined by a "continuous miner" that cuts a network of "rooms" into the seam. As the rooms are cut, the continuous miner simultaneously loads the coal onto a shuttle or ram car where it will eventually be placed on a conveyor belt that will move it to the surface.
