The gold was usually found in the form of dust or flakes. You might get a pinch or so in each pan, and you could wash 50 pans a day . . . if your back held out--and if the icy water didnt cripple your hands and legs. Panning was always used to try out a new prospect. But the miners learned from experience how to handle more dirt by other means. Hydraulic mining uses water power to fracture and transport a bench of Earth or gravel for further processing. Hydraulic mining is used for placer deposits of gold, tin, and other metals. Surface mining equipment is similar to construction equipment (e.g., scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines).

Drift mines have flat entries into the coal seam from a hillside. Drift mines are different from slope mines, which have a tending opening from the surface to the coal vein.

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal. Jan 12, 2021 A method of short-hole mining, cut-and-fill mining is used in irregular or steeply dipping ore zones, especially where the hanging wall limits the use of long-held methods. The ore is mined either in slightly inclined or horizontal slices then it is filled with sand, waste rock, or tailings.
