  • 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.. Hydraulic mining originated out of ancient Roman techniques that used water to excavate soft underground ...

    Hydraulic mining is also likely to find good application with our friable and moderately soft coals. The advantages of hydraulic mining are – winning of coal is not hindered by bringing of face support, the system is not very sophisticated to warrant complexity of adoption, higher output per working face results with steeply inclined seams.

  • Hydraulic Mining Equipment

    Hydraulic Mining. Where it is practicable, this is the simplest and most inexpensive method of placer mining. The mechanical equipment requirements consist only of pipe lines and giants. One feature, however, that is frequently overlooked in hydraulic mining is the matter of dumping facilities. This should always receive careful consideration.
