The underground mine is a block caving operation, the first such system to be used in metal mining in South Africa. With the introduction of the underground operation, the output of ore has fallen from the 82,000t/d achieved in the previous open pit to 30,000t/d.
STABILITY EFFECTS AND FAILURES FROM EXTENSIVE METAL …
regional hard rock mining in several case studies of shallow stope cave-in failures. Applicable numerical modeling methods indicate that destressing of the rock mass is in effect under such extensive mining, which facilitates the occurrence of block caving, raveling and plug failures in effectively fissured rockmasses. 1.

Underground mining (hard rock) - Wikipedia
Block mining methods . Block caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated between the top of the haulage level and the bottom of the undercut. The drawbells serve as a place for caving rock to fall into.
