Mine hoists are advanced machines employing hydraulics on essential functions such as the brake and clutch. A hoist (or elevator) carries not only ore and machinery but also precious human cargo. In fact, some hoists lower and lift hundreds of persons more than two miles (three kilometers) into the dark depths.

Hydraulic Mining in California. By Craig E. Crouch, Rocklin, California . Hydraulic mining uses jets of water to break down gold-laden gravel banks and to wash the material through gold-separating devices (sluices and under-currents). It was one of the dominant forms of the California gold mining industry from the mid-1850s until 1884, …
