"Raise Caving" – Cheaper and more flexible mining at great ...

Mass-mining methods, such as block caving or sublevel caving, enable low-cost and efficient mineral extraction, but these methods are associated with high capital cost and risks. Latter mining methods call for mine planning and decision many years in advance. Moreover, block caving and sublevel caving are difficult to apply in at great depths due to the high prevailing stress conditions.

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 ...

Sublevel Caving - Oraee

Sublevel Caving. In this method, the stope is divided into sublevels, fairly close to each other, normally with 8-15m vertical interval between each two adjacent ones. These sublevels are called sublevel drifts or production drifts. Production is carried out from the sublevel drifts by means of long holes above the end of the production drifts.
