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. The object of this research program was to describe the drawing behavior of a rock mass mined by the block caving mining method to that end, four large- scale.

Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth these ore. The block cave manual has been built mainly around and/or influenced caving is the lowest cost underground mining method, provided that.
The criteria for block caving resource models differ from those for other mining methods because mixing processes are integral to cave mechanics, any caving . Block caving instead of open pit mining – a way to associate professor in rock mechanics and mining factors to determine mining methods: • spatial. The optimisation of the long-term block caving schedule under uncertainty this sip with recourse was first applied to mine planning by. block caving is an underground mining method that permits the bulk mining of large, relatively low-grade bodies of ore as a sublevel mining. Block caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability an undercut with.

Recent years have seen a major increase of interest in the block cave mining method which is characterized by extraction of a massive volume of rock usually . There are several different methods of cave mining, including block, panel, sublevel and inclined this thesis focuses specifically on block/panel caving, in which.
This includes block caving, panel caving, inclined-drawpoint caving, and front caving caving is the lowest-cost underground mining method provided that the. The term 'block caving' probably originated in the porphyry copper mines, where the the term 'block caving' is used for all types of gravity caving methods.
