Hydraulic mining utilizes the force of water sprayed under high pressure to extract coal. Hydraulic mining utilizes continuous miners to mine entries to gain access to production panels. Once a production panel is established, high-pressure water cannons are used to break the coal off the face.

Hydraulic gold mining in the Sierra Nevada, California (1853–1884) displaced ~1.1 billion m3 of sediment from upland placer gravels that were deposited along piedmont rivers below dams where floods can remobilize them. This study uses topographic and planimetric data from detailed 1906 topographic maps, 1999 photogrammetric data, and pre- and post-flood aerial photographs to document

The old hydraulic-mining sluices, in which grizzlies and undercurrents played such an important part, and the early pick-and-shovel telescope-boxes, used even now in some fields, show that, in order to save gold directly, the current must be below that required to move coarse gravel, since otherwise the gold will go with the gravel to the tail

Douglas Beckstead, 1995. Figure 1. When thawing operations ceased at Coal Creek the hydraulic pipes were gathered and stacked according to size and use in what is now called the Coal Creek Pipe Yard. The pile of black rubber hoses carried water from the pipes to the cold-water points. The curved goose-neck pieces in the foreground connected the

Large mining companies saw the potential for profit if they could find a way to process large quantities of gold bearing gravel in quick order. The process called hydraulic mining, or “hydraulicking” became widely used. Hydraulic mining uses high pressure jets of water to dislodge sediment and material for processing.

But hydraulic mining was still widely used in placer gold mines on Alaska in the early 20 th century. Today, hydraulic gold mining is only rarely practiced on an industrial scale, but gold mines on Alaska sometimes use it. It survives mostly in artisanal form in remote, undeveloped and largely unregulated areas of the world.

Hydraulic gold mining sediment in northern California provides an unusual opportunity to study sediment transport and mixing in a large, well-documented deposit.

recovery and concentration of gold. In 1852, a French-speaking Canadian miner named Anthony Chabot bypassed the need for ditches and flumes by hooking up a canvas hose and directing the water flow at the ore supply. When his partner, Edward Mattison, increased the water pressure by adding a nozzle to the hose, hydraulic mining was born.

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. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold.

Unlike hardrock mining, which extracts veins of precious minerals from solid rock, placer mining is the practice of separating heavily eroded minerals like gold from sand or gravel. The word placer is thought to have come from Catalan and Spanish, meaning a shoal or sand bar. The word entered the American vocabulary during the 1848 California
