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 ...
