Opencast Mining an overview ScienceDirect Topics

Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 ).

Analysis of main factors influencing the apertures of

17/04/2020· It is revealed that main factors influencing the apertures of mining-induced horizontal fractures are thickness of extracted coal seam, distance from extracted coal seam to horizontal fracture, uniaxial compressive strengths of rock layers above and below the fracture, thicknesses of rock layers above and below the fracture, and thickness of “layer-bridge” (key strata).

Coal Mining and Regional Economic Development

Abstract Coal mining did not curse the long run development of Pennsylvania’s anthracite and bituminous regions. From 1850 to 1950, mining positively impacted the economies of the state’s coal counties, especially the bituminous-producing counties. As manufacturing production became more energy-intensive around the turn of the century, proximity to cheap coal became an important cost

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
