Introduction. Block Caving is an underground mining method in which high productivity and low operational costs are expected when applied to thick low-grade ore bodies. 1, 2 Using this process, the broken ore is extracted from the bottom of the ore body after the initial undercutting. The undercutting induces progressive rock mass caving …
