Hydraulicking: Water duty varies widely and reflects the coarseness of gravel, degree of cementing, height, of bank, grade of bedrock, available head, etc., and is commonly between 1/2 and 7 cubic yards per miner's inch-day. This would be equivalent to about 2,000 to 32,000 gallons per cubic yard.
During the Gold Rush period, placer mining was heavily dependant on manual labor and the use of water, so its mining sites are typically found along streams, in river canyons, or in tributary canyons. Typical mining equipment during the period included cradles, long toms, sluice boxes, and hand-held equipment (pans, picks, shovels, etc.).

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.
Hydraulicking utilizes a high-pressure stream of water that is directed against the mineral deposit ... of equipment. Since mining is composed of a la rge number of heavy and mechanical components
Hydraulicking in the mountains could bury valleys in unusable tailings. The farmers of the Sacramento Valley actually sued miners on the basis that hydraulicking was ruining their farms. In Montana, you can still see evidence of extensive hydraulicking around both Bannack and ia City, as well as many of the other mining ghost towns in ...

Hydraulic mining is employed principally for excavating thick deposits, but in Alaska it has been used widely for mining creek placers and bench deposits, many of which are but slightly above the creek level. Hydraulicking or "piping" also is used to remove the overburden from the pay gravels, the latter then being mined by other methods.
Mining equipment can vary depending on the work being done. Here are the more common types of equipment that you may need. Mining drills are more common with underground mining. Drilling helps to bring material to the surface so that it can be further processed.
