Underground mass mining methods present several geotechnical challenges and risks inherent with block cave mining environments Underground mining methods such as block panel and sub level caving continue to be the primary choice for deeply situated massive orebodies due to the high production rates and low operating costs involvedJul 25 32 Block caving is a new alternative method of developing new mines or extending the operation of open pits Block caving is an underground hard rock mining method that involves undermining an ore body allowing it to progressively collapse under its own weight It is the underground version of open pit mining

Sublevel Caving Sublevel Caving is one of many different methods for underground hard rock mining It is a large scale mining method suitable for large ore bodies with a steep dip and a rock mass with a host rock in the hanging wall will fracture under controlled conditionsBlock caving definition a method of mining a large block of ore by systematically undercutting so the ore will cave See more

Describe the Block Caving Method Block is the mining layout which divides the orebody into sections Caving of the rock mass is induced by undercutting the block >the rock section underneath the block is fractured by blasting which destroys its ability to support overlaying rockLater in the schedule the company is also targeting the outlying Kucing Liar orebody for block caving In the meantime FCX converted its DOZ orebody which it began mining in using open stoping to block caving in with production expected to continue until
