WebMining Optimization Laboratory (MOL) University of Alberta, Edmonton, Canada . Abstract Long-term mine scheduling is among one of the optimization problems. Block caving technique is a mass mining method in which gravity is used in combinationwith internal rock stresses to fracture and break the rock mass into pieces that can be handled by miners. WebMar 1, 2024 · When the drawpoint spacing decreases, the number of ore drawpoints increases, and hence results in increased ore recovery. The close spacing of drawpoints also results in draw ellipsoid interaction resulting in reduced residual ore in the stope.
