Hydraulic Mining. Hydraulic mining, or hydraulicking, is a type of mining that uses water to displace rock material or move deposit. Formerly, the use of a huge volume of water had been urbanized by the Romans to take out overburden and then gold-bearing debris as in Las Médulas of Spain, and Dolaucothi in Britain.

Hydraulic Mining as we know it was first used in 1853 outside of Nevada City, California by Edward Matteson. He used canvas hoses to redirect water and dislodge gravel. As the more easily accessible gold deposits in California were depleted, miners generally had two choices: hard rock mining or hydraulic mining.

The benefits of hydraulic use in mining include the fact that the equipment can operate at a specified pressure to take advantage of the force exerted by the larger cylinder to achieve massive force and lift heavier loads. During mining, double-acting cylinders give the operator more control, particularly when moving rocks and objects downwards.

Who Invented Hydraulic Mining? It is also used in mining kaolin and coal. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits. Its modern form, using pressurized water jets produced by a nozzle called a "monitor", came about in the 1850s during the California Gold Rush in the United States.
