Backfill

The use of hydraulic backfill systems became common in the 1940 s and 1950 s Following serious mine accidents involving placement of straight tailings in underground openings removal of the finer portions of mill tailings to control percolation was initiated and implemented The 100 mm 4 percolation rate became the industry standard.

Hydraulic mining

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.
