摘要
讨论了在岩爆防治中能量释放控制的的重要性。在以能量释放率作为衡量指标对冬瓜山铜矿深埋矿床采场结构参数和开挖步骤进行数值分析的基础上 ,提出控制能量释放的合理采场结构参数和开挖步骤。结合该矿岩爆现场调查资料、采矿方法以及支护原理 ,分析并提出控制巷道及采场围岩能量释放的支护及工程处理措施。
The importance of the energy release control in rock burst prevention and treatment was discussed.Based on their numerial analysis of Dongguashan deep laying copper deposit with the energy release rate as the measuring index,the stope structural parmeters and excavation steps rational for controlling the energy release were put forward.Considering convprehensively the in situ investigation data of rock burst and the mining method and support principles of this mine,the measures for the support and engineering treatment in controlling the energy release of the surrounding rock of workings and stope were suggested and analysed.This research achievement has been used in the mining design and construction of the mine.
