Types of Underground Mining Method Comparison

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 ...
