2018-1-25 · Surface mining: The mining technique is used when the coal seam is present near the earth’s surface. The techniques followed in surface mining include open-pit mining, strip mining and mountaintop removal. While open-pit mining involves extraction of coal from an open pit in the ground, strip mining includes stripping surface layers to reachModern Mining Underground Anglo American,Modern mining increasingly uses automated techniques. We are using automated and continuous rock cutting vehicles to safely extract the targeted ore deep underground without the need for explosive blasting, thereby creating far greater rock stability and far less variance in the quality of the ore we extract.

2016-2-3 · Bell Pit Mining. Bell pit mining was one of the early methods of underground mining. The name comes from the shape that the mine forms. A long narrow shaft is dug down until it reaches the coal seam. Once it reaches the seam, the coal is then mined laterally along the seam either side of the shaft, creating the bell shape.Mine Tailings Disposal Methods,2017-6-16 · Room-and-pillar mining may leave as much as 60 percent of the coal in supporting pillars after initial mining. Later, some of these pillars are removed as equipment retreats from the mined area. Long-wall mining permits increased recovery of coal by extracting coal along a single face which is much longer than used in room-and-pillar mining.
