  • Definition of block caving

    The term block caving probably originated in the porphyry copper mines, where the area to be mined was divided into rectangular blocks that were mined in a checkerboard sequence with all the ore in a block being removed before an adjacent block was mined. this sequence of mining is no longer widely used. today most mines use a panel system.
