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 highpressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting watersediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.

For many years, machines have been used to continuously excavate soft minerals in underground mines. In some cases, this includes the soft, or weak, rocks that surround the valuable mineral being extracted. Coal is probably the most common example. Much of the mine development tunnelling in underground coal mines is done in coal.

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.
