Sub Level Caving

 · Experience from LKAB, Sweden - Sub-level caving (SLC) is an important mass mining method, used at LKAB. The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses.

Types of Underground Mining Method Comparison

 · 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 blasted out with one large blast.
