    Jul 14 2014 · Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving. Block caving is the mining method in which masses panels or blocks of ore are undercut to induce caving permitting the broken ore to be drawn off below. If the deposit is overlain by capping or bounded by drawing the ore.
