2. Mining Methods Copper

2021-1-21  Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops. In both mining techniques, the mined ore must be removed from the mine

Copper Mining Process Operations Minto Explorations

2021-5-20  The Minto mine commenced Yukon mining operations in 2007 as an open pit mine. In 2012 the company began underground development on the Minto South Deposits while continuing to mine additional open pits as the primary mining method. Today, the mining is entirely underground and we are currently producing in the Copper Keel ore body.

Mining Resolution Copper

Mining. The most viable way to recover the ore body is by a well-established underground mining method called block caving. Block caving is safe, environmentally sound, and cost-effective for mining a large, deep orebody. In block caving, a large section of ore is initially undercut by drilling and blasting, causing it to collapse under its weight.
