Coal Mining High Pressure Water

  • Hydraulic mining Wikipedia

    Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.

    17-3-2015· This responsibility falls to the roof support systems that are powered hydraulically by a number of high pressure pumps. The principle of longwall mining is the use of a large cutting head or shearer which traverses the coal seam breaking it up and depositing the coal onto an armoured conveyor to transport the coal away from the face of the mine.

  • Coal mining Wikipedia

    Coal mining greatly increased during the industrial revolution and the following decades. The main mining areas were around Aachen, the Ruhr and Saar area, along with many smaller areas in other parts of Germany. These areas grew and were shaped by coal mining and coal processing, and this is still visible even after the end of the coal mining.
