Surface Mining, Industry of Metals, Minerals, Precious ,Coal mining

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnelsCoal mining, extraction of coal deposits from the surface of Earth and from underground Coal is the most abundant fossil fuel on Earth Its predominant use has always been for producing heat energy.

Surface Coal Mining

Surface Coal Mining The primary methods of surface coal mining used in Pennsylvania are: Strip Mining: Layers of soil and rock overburden are removed the coal exposed coal seam is excavatedStrip mining is the process of scaping the coal from the top surface of the ground The problem with peat is that it has a very low heat value per kilogram of the fuel burned In addition, strip mining is ecologically very destructive unless the mining company makes a.

Surface Mining

Considering the latter, surface mining includes: Large-scale opencast mines that are kilometres long and wide, and more than 300 metres deep Mines such as these supply manganese, iron ore, chrome, diamonds, platinum and coal;In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it.

Coal mining

Surface mining is only economic when the coal seam is near the surface This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited - 90% or more of the coal can be recovered"overburden" (rock above the coal seam), and "interburden" (rock between coal seams) Overburden and interburden are disposed of in adjacent valleys because the broken rock will not all fit back into the mining pit, and disposal alternatives are limited The usual method of disposing of this excess.
