  • Hydraulic mining - Wikipedia

    OverviewHistoryContemporary usageUnderground hydraulic miningSee also

    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 developed from ancient Roman techniques that used water to excavate soft underground deposits. Its modern form, using pressurized water jets produced by a nozzlecalled a "moni

    Hydraulic mining, use of a powerful jet of water to dislodge minerals present in unconsolidated material, including mine tailings, placer deposits, alluvium, laterites (soil rich in iron oxides), and saprolites (soil rich in clay). It has also been applied to consolidated materials from sandstones through coal to hard rock. Hydraulic mining encompasses hydraulicking, sluicing, and educing.

    24/08/2018  The benefits of hydraulic use in mining include the fact that the equipment can operate at a specified pressure to take advantage of the force exerted by the larger cylinder to achieve massive force and lift heavier loads. During mining, double-acting cylinders give the operator more control, particularly when moving rocks and objects downwards. In the event that the load carried at the mining ...

    The earliest attempts at hydraulic mining involved transporting coal from the mine mouth to the nearest road or rail transport.

It was soon discovered that wood was rapidly worn away, so the flume was lined with iron ...
