Sublevel caving is an effective mining method for steep ore bodies, allowing maximum extraction from the ore body with a high degree of safety. The mining in the underground mines takes place in a 'drillandblast cycle', a process that includes activities ranging from development to hoisting during the course of a day. Underground mining takes place in several stages: Drifting. In order ...
