Coal | National Geographic Society
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.
Coal mining - Wikipedia
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a pit, and ...

Coal extraction - Eniscuola
Coal extraction. The set of operations leading to the identification of coalfields and to their assessment is called mining prospecting. As with oil, an analysis of airplane pictures is conducted to identify geologically interesting areas, then soil samples are studied to obtain more detailed information. After having identified the coalfield and its position and shape, the mine building site ...

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. Self-advancing, 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 ...
