Impact of Coal Mining on Environment
The burning of coal releases harmful substances such as sulphur dioxide, nitrogen oxide, carbon dioxide, as well as particulates of dust and ash. Dangerous levels of air and water pollution have been recorded in coal burning areas. It is globally accepted that coal mining adversely affects the local and global environment. Mining adversely affects the local environment in that it destroys ...
Land Subsidence in a Coal Mining Area Reduced Soil ...
Underground coal mining in western China causes heavy land subsidence and alters the soil ecology. However, the effects of land subsidence on soil fertility are not currently known, and the key factors governing its impact remain unclear in sandy land. We investigated the effects of land subsidence induced by underground mining on the soil quality in western China. Soil samples were collected ...

Coal Geology | Geoscience Australia
Many underground coal mines in Australia use longwall mining methods, which enable extraction of most of the coal from a seam using mechanical shearers. The mining 'face' can be up to 250m long. Selfadvancing, hydraulic powered supports temporarily hold up the roof while the coal is extracted. The roof over the area behind the face, from which the coal has been removed, is then allowed to ...
