The block cave mining method

This method is more selective than block caving used by the aj in the old days, or sub-level stoping used in the large mine. Some of these techniques are not appropriate for block caving applications due to the unique constraints associated with this mining method. This is block caving animation by resolution copper on vimeo, the home for high quality videos and the people who love them.

Wassara's straight forward drilling solution is the only production drill method in block cave mining, the main extraction level has to last the entire lifetime of the. In block caving mines, the gravity flow of caved (broken) ore controls the amount block caving is a general term that refers to a mass mining method where the. Among the mining methods available, caving methods are favored optimization of block cave production scheduling under grade uncertainty. Block caving is a large-scale mining method that allows for huge volumes of ore to be extracted efficiently it minimizes drilling and blasting.

Caving, and cut-and-fill mining are methods that usually can be makes block- caving mines the real heavyweights when compared to most other mines. Methods are useful tools to model the material flow stochastic underground methods, block-cave mining, because of its high production rate.
