There are several different types of underground mining but the most common variant is called block caving. This type of mining for diamonds was first introduced at the Kimberley mine in 1951. It relies on the kimberlite rock being weaker than the surrounding host rock material.
Types of Gemstone Mining Methods. Undersea or Marine Mining: This type of mining is used wherever there are marine deposits. These may be on the beach, as in the Namaqualand diamond deposits in West Africa, or they may be off shore deposits. This type of mining may involve land reclamation or even deep sea dredging.

Type of surface mining that uses explosives, massive shovels, and even larger machinery called draglines to remove rock/earth to expose seams of coal underneath a mountain. CONTOUR MINING. Form of mining used on hilly or mountainous terrain. A power shovel cuts .
Hydraulic mining was a variation on ground sluicing where the water delivered to the site would be shot through a nozzle at high pressure onto the face of the cliff, thereby washing away tons of boulders, gravel, dirt, and gold.
Hardrock (Lode) Mining. In both kinds of hardrock mining, the ore is then processed in some manner to remove the gold. Usually this entails crushing the rock into powder and using some combination of gravity, centrifugation, and "froth flotation" to perform an initial separation of gold from rock.

Mining allows humans to use these resources. Some mining practices are controversial. Mountaintopremoval mining, for example, allows mining companies to extract a significant amount of coal at a far lower cost, but its destructiveness has led to protections for the environment. Traditional forms of mining can be unsafe for workers.
