Paper: Increasing Productive Capacity In Block Caving Mines

Paper: Increasing Productive Capacity In Block Caving Mines

Abstract The block caving method requires the effective management of the induced stress conditions and the ore production system. We believe that the primary focus should be on the strategic design of the ore production system that will facilitate the management of the development activities involved in expanding the production footprint.
