    Mar 16, 2017 Block caving is an extreme case of sublevel caving in which instead of a back of ore 5 to 10 ft. thick, one 50 ft. thick is undermined and allowed to cave. The method is illustrated in Fig. 7. After the bottom of the block, or panel, is cut up into pillars by drift’s and cross drifts, the pillars are robbed, and then the remaining stumps are

    How Underground Mining Works | HowStuffWorks

    Mining in Bulk: Block Caving. The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as
