Hydraulic Mining - Yuba-Sutter - LocalWiki

Hydraulic mining was a form of mining that used water to dislodge rock material or move sediment. Typically, intense jets of water were pressurized in an ever-narrowing downward channel or hose and aimed at a hillside or riverbank, shearing off huge amounts of land and breaking it apart, washing the resulting debris into a huge sluice that extracts the gold from it.

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 developed from ancient Roman techniques that used water to excavate soft underground deposits.
