mining and mines
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 LHD system for very coarse material.

74. Mining and Quarrying
Properly applied, block-caving is a low-cost, productive mass mining method. However, the amenability of a rock mass to caving is not always predictable. Also, the comprehensive development that is required results in a long lead-time before the mine starts producing: the delay in earnings can have a negative influence on the financial projections used to justify the investment.
