    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 called a 'pit

    Almost 1,800 miners have died in France in coal mining disasters since 1876. More than 6,000 miners died in China in mining accidents in 2004, while 301 were killed in a mining accident in Soma, Manisa province, Turkey on May 13, 2014. And between February 25 and 28, 2016, 36 miners were killed by a series of methane explosions in a coal mine in Vorkuta, Russia, more than 100 kilometers north

    4 Coal Mining and Processing Coal: Research and

    The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary

    Appendix E: Coal Mining and Processing Methods Coal

    In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the

    22/12/2012· Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth’s surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground. The immediate environmental impact of underground mining appears
