    Project Overview Resolution Copper

    Project Overview Resolution Copper.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.

    El Teniente QueensMineDesignWiki.As mining has progressed and larger depths have been reached, the exploitation of only primary ore has resulted. The primary ore consists of soft, higher-stress, low-grade ore zones that fracture easily, often violently. Due to these conditions, the mine has changed over to mechanized ore transfer with panel-caving and block-caving methods.
