advantages of surface mining of coal compared to underground mining

Surface miners drive up savings in coal mining

Significant advantages emerged when working with the surface miner, which produced 14% fewer fines at grain sizes of less than 2 mm compared to the conventional mining systemSurface mines offer advantages and disadvantages when compared to underground mining Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rat.

advantages of coal mining

Drift mining is either the mining of an ore deposit by underground methods, or the working of coal seams accessed by adits driven into the surface outcrop of the coal bed A drift mine is an underground mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into the ore seamSurface 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.
