  • Cave Mining Today's Challenges

    The industry perception is that sublevel caving is a "dirty mining method" (i.e. high dilution and low recovery). However, there were several successful sublevel cave mines executed in the past. The success of a sublevel cave mine is not by chance they are engineered to perform.

    Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades. Depending on how the ore is broken there are three block caving systems 1) The Grizzly system for fine material, 2) the slusher system for coarser material and 3) the

    7. Sublevel caving. Sublevel caving is a method often evaluated in parallel with block and/or panel caving options. It requires multiple levels of development and ongoing ring blasting for production. Sublevel caving allows for a more selective extraction but typically achieves lower production rates than block and panel caving methods.
