Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining .
The coal mining process followed by the soil construction usually reduces the SOM, which can facilitate the soil degradation. The loss of SOM and, consequently, the decrease of the microbial population, affect the soil's physical restoration as well as the re-vegetation process (Grayston et al., 2004). The SOM, the microorganisms, and the ...
[PDF]Coal mining is the process of getting coal out of the ground. It is part of the mining industry.Coal is used as a resource for making electricity.. Extraction. Surface mining is done when the coal is near the surface. Coal miners remove the soil above the coal. The coal can then be removed without the coal miners having to go deep underground..

They often complain about it because it is full of water and produces lots of greenhouse gasses to burn(In the driest, inhabited continent, we complain of something being .
Surface mines (sometimes called strip mines) were the source of about 65% of the coal mined in the United States in 2017. These mining operations remove the soil and rock above coal deposits, or seams. The largest surface mines in the United States are in Wyoming's Powder River Basin, where coal ...
They selected 14 samples of soil from a dam at the mining site, 13 soil samples from an area near the mine and 20 soil samples in a site relatively far from the mine. The soil samples were selected twice, each in March and in August 2006. The amounts of heavy metals in the mining site were then compared with the surrounding areas.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash.Any material that cannot be grown through agricultural processes, or created artificially in a laboratory or ...
The environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products.In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that contain ...
Opencast coal mining has a series of consequences on land resources and places enormous pressure on the ecological environment. Stripping, excavation, transportation and dumping have different effects on soil physical, chemical and biological properties.
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
Vegetation restoration is an available way to ameliorate degraded lands. In order to study the response of soil microbes to vegetation restoration in coal mining subsidence areas, the composition ...
Jul 01, 2001 · Reclamation of coal-mining sites demands special consideration of challenging environments, particularly in mountainous areas. Reclamation specialists, whether mining company employees, independent contractors, or representatives of regulatory agencies, have developed innovative approaches to returning mining sites into productive habitat.
