Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead.It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt ...

C ontinuous mining systems have been established in coal and soft rock mining for about a century now and the technology to cut through hard rock has been successfully used in civil engineering projects since the late 1950s. One would think that by now, continuous hard rock mining would also be a reality but it is not. The possibility of the technology being applied to hard rock …

Underground hard-rock mining accounts for 40 percent of global mining operations but only 12 percent of run-of-mine (ROM) production. 1 Underground mines also tend to be more targeted, more costly, and less productive than open-pit mines. Because the choice of which underground method to deploy is predominantly driven by the geology of the deposit being mined, the operator has little ...

While Europe (as well as other parts of Britain) specialised in surface and underground coal mining i.e. soft-rock mining, the Cornish mining industry toiled to release metals embedded in hard rock, such as lead, copper, zinc, silver, nickel and tin and thus Cornishmen became world leaders in deep level hard rock mining, at least until the ...
