Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
Tracking the trends 2017 02 Where to play, how to win These divergent views of the industry's prospects emphasize a widening gulf in the sector. It seems no longer possible, if it ever was, to discuss the mining industry as a cohesive whole. This largely explains why so many companies are adopting such different strategic responses.

Surface mining. 4 Main Types of Surface Mining. Strip Mining. Removal of large strips of overlying rock and soil to reveal coal. Open-Pit Mining. Removal of rock and soil creating a vast pit where coal can be extracted. Mountaintop Removal Mining. Removal of mountain tops with explosives. Land made flat after reclamation. Highwall Mining
Coal is mined by two main methods : Underground or 'deep' mining Surface or 'open-cut' mining The choice of method is largely determined by the geology of the coal deposit, in particular the depth of the seam below the surface. The majority of the world's coal reserves are recoverable by underground mining.

Surface mining methods dominate the world production of minerals. Currently, almost all non-metallic minerals [more than 95%], most metallic minerals [more than 90%] and a large fraction of coal [more than 60 percent] are mined by surface methods.
of bituminous coal and drilling for petroleum and natural gas. Portions of the watershed are affected by severe AMD that originates from several surface coal strip mines and a few abandoned deep shaft mines. Although mining activity ceased in the late 1930s, water quality problems persist to this day at several locations.
productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit. In this paper, we focus speci cally on the truck and loader equipment selection problem for surface mines.
