The need to use hydraulic technology for washing out quaternary bedrock, as well as heterogeneous rocks previously piled in hydraulic-mine dumps located above commercial coal reserves, requires the use of modern high-performance equipment. As such equipment, it is advisable to use the new GD-300 hydraulic mining giants - monitors, which are designed, manufactured and tested at Kuzbass open

Hydraulic mining Last updated October 03, 2020 A miner using a hydraulic jet to mine for gold in California, from The Century Magazine January 1883. Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. [1] In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold.

Hydraulic Mining was a gold recovery method that was used during many of the gold rushes around the world during the 1800’s. It was used extensively in California's Mother Lode county during the famous gold rush there. One of the problems that the early California gold miners faced with basic placer mining was the amount of manual labor that was required to process the gravels.

Water was redirected into an ever-narrowing channel, in the course of a large canvas hose, and out a giant iron nozzle, known as a monitor. The tremendously high pressure stream was used to wash complete hillsides through huge sluices. By the early 1860s, while hydraulic mining was at its height, small-scale placer mining was a thing of the past.
