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 drifts and cross drifts, the pillars are robbed, and then the remaining stumps are ...

Design Of A New Layout For Sublevel Caving At Depth

Abstract LKAB has been mining iron ore with the sublevel caving mining method in northern Sweden for more than 60 years. Throughout the years, LKAB has improved this mining method to stay competitive in a tough international iron ore market. Improvements in drilling and blasting technology have helped LKAB increase the scale of sublevel caving and therefore decrease its mining costs in ...

Sublevel Caving Archives International Mining

Sublevel Caving SLC was selected as the mining method for the underground portion of the deposit based on the amenable geometry of the deposit, and because productivity and cost advantages of SLC enable greater exploitation of the underground resource at greater margin than more selective mining methods, Atlantic Nickel said.

Compare Stoping Methods Of Mining

Apr 05, 2017 Sublevel caving lacks the flexibility of supported-stope methods but is more flexible than block caving. The sublevel development serves to explore the ore body at each caving horizon before mining begins, and irregular boundaries can be followed more easily than with block caving and with less dilution from the walls.

slice. Mining continues upwards towards the surface until the ore body is depleted. Sublevel Caving Sublevel caving is usually carried out when mining of the ore body through an open pit method is no longer economically feasible. Mining now proceeds underground, underneath the open pit. At first, both a raise and a network of tunnels are made.
