Caving Process 65 30 45 55 Cave mining is based on the principle that once a sufficiently large area of a block has been undercut by drilling and blasting the overlying block of ore will start to cave under the influence of gravity. The process will continue until caving propagates through the entire block to

BLOCK ANd pANeL CAVING Block caving is an underground mining method that uses gravity to exploit massive steeply dipping orebodies located at depth particularly those with disseminated mineralisation or that are low-grade in nature but too deep to be extracted using open pit methods. Block caving also depends on insitu stresses and

Production Scheduling With Horizontal Mixing Simulation In

Apr 21 2020 High production rates and low operating costs highlight block caving as one of the favorable underground mining methods. However the uncertainties involved in the material flow make it complicated to optimize the production schedule for such operations. In this paper a stochastic mixed-integer linear optimization model is proposed in order to capture horizontal mixing that occurs among
