Underground mining (hard rock) - Wikipedia

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, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.

Integrated mining, pre-concentration and waste

The concept is proposed as a Lean Manufacturing approach to hard rock mining, as an alternative to improving the economics of mining simply by increasing the mining rate. Lean Manufacturing philosophy seeks to design out overburden, smooth production, and eliminate waste from the system. It is suggested that the introduction of these systems into the hard rock mining process addresses all three of theseMining Equipment Projects - Rock Systems, Inc.,Nordic - Parks Bar Quarry - Rock Systems, Inc.
