摘　　要：桦树沟铜矿铜矿床位于铁矿床深部,因而地质构造复杂,为了掌握桦树沟铜矿区地压动力灾害发生过程和规律,在铜矿区建设一套微震监测系统。微震监测系统台网设计是关键的一步,台网布设的优劣会影响到微震事件的定位精度,进而影响监测效果。本文通过现场调研和岩石力学分析方法得到矿山主要地压灾害危险区,基于该区域采用台网设计工具得到最优的监测设计方案并通过现场验证方式检验设计效果,研究结果表明该微震台网的优化设计方法可以大幅度提高地压灾害预警的准确性。Huashugou copper mine is located in the deep of iron deposit,so its geological structure is complex.In order to master the occurrence process and rules of ground pressure dynamic disaster in Huashugou copper mine,a set of microseismic monitoring system is built in it.The design of microseismic monitoring system is a key step,because the layout of the network will affect the positioning accuracy of microseismic events,and then affect the monitoring effect.In this paper,the main ground pressure hazard area of the mine is obtained by field investigation and rock mechanics analysis.Based on this area,the optimal monitoring design scheme is obtained by using the network design tool,and the design effect is tested by field verification.The results show that the optimal design of microseismic network can greatly improve the accuracy of ground pressure disaster warning.
