Application of short-hole induced caving sublevel open stope mining method in a gold mine
In response to problems such as the development of rock joints and fractures in a gold mine,poor sta-bility of the ore body,difficulties in preliminary mining and support,and poor safety in recovery,experimental research on the short-hole induced caving sublevel open stope mining method was carried out in localized fractured areas of the ore body.The method utilizes the mechanical properties of the rock itself and the caving stress field controlled by artifi-cial engineering to cave crushed ores.The study provides a detailed introduction to the structural parameters of the stope,the layout of mining and cutting engineering,undercutting,and ore caving processes.Field applications have shown that with the implementation of this method,the production capacity of the stope reaches 127 t/d,the mining loss rate is 9.2%,and the ore dilution rate is 14.6%,achieving good results.It has reference value for the safe and efficient recovery of similar ore bodies.
