Block Caving - Mining Fundamentals

Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization. "Block" refers to the mining layout, which divides the ore bodies into blocks and large sections.
