  • 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 Mining 101 The Coal Seam

    These tunnels are situated in coal seams so as the machinery advances further underground, coal is removed. Using a combined system of vehicle haulage and conveyor belts, the coal extracted from the seam is transported to the surface. Underground mining is practical from engineering and safety standpoint for coal seams that are located more than 100 feet below the surface of the land

  • Appendix E: Coal Mining and Processing Methods

    Longwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates, feasible only in relatively flat-lying, thick, and uniform coal beds. A high-powered cutting machine (the shearer) is passed across the exposed face of coal, shearing away broken coal, which is continuously hauled away by a floor-level conveyor system ( Figure E.2 ).

    Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earth’s surface (outcrop). Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s.

  • What Is Coal Mining Some Interesting Facts

    The two major schools of coal mining are surface mining and underground mining. To qualify for surface mining, the coal seam must lie within 60 metres of the surface. The miners’ job is to remove all of the ‘overburden’ the cubic tons of rock, soil and trees above the coal seam -and expose the coal layer for extraction. The main tools of the trade are dynamite and dragline excavators

  • Underground v.s. Surface Coal Mines: Is

    Coal mining typically requires two methods of operations: underground and surface mining. The method is differentiated by whether the seam is relatively close to the surface area or buried deep below.
