Block cave mining video
WebBlock caving is a large-scale mining method that is particularly useful for mining low-grade or disseminated ore bodies which are at too great a depth to be exploited through open-cast mining. This mining technique gets its name from the layout of the mine which divides the ore into large sections or ‘blocks’. Web3. Block cave production scheduling The production rates of a mining system are defined by production planning. In underground mining, the extraction and rates of production should be scheduled during the life of the mine from feasibility through to the final production phase. In the case of a block cave mine, the production
