摘　　要：针对铜绿山矿地压显现等现象,建立了16通道的深部地压微震监测系统。对微震事件的波形、时间分布规律和空间分布规律进行了分析,并采用视体积和能量指数对矿山岩爆灾害进行了预测。调试结果表明:微震监测系统的定位误差在20 m以内,能够满足矿山微震监测的需要。微震活动与采矿活动联系紧密,在时间上主要表现为两个活跃期,分别为14∶00时间段和15∶00时间段。在空间上,微震事件在-665 m中段东北侧附近区域和-845 m中段三穿北侧附近区域表现为聚集现象。预测结果显示,矿山短期内发生岩爆灾害的可能性不高。In view of the phenomenon of ground pressure in the Tonglushan mine,16 channel deep ground pressure microseismic monitoring system is established.The waveforms,time distribution law and spatial distribution law of microseismic events are analyzed,and the mine rockburst disasters are predicted by apparent volume and energy index.The debugging results show that the positioning error of the microseismic monitoring system is less than 20 m,which can meet the needs of mine microseismic monitoring.The microseismic activity is closely related to the mining activity,and it mainly shows two active periods in time,which are the 14∶00 time period and the 15∶00 time period.In space,the microseismic events appear as a clustering phenomenon in the northeastern region of the middle section of-665 m and the northward zone of the middle of-845 m.The prediction results show that the possibility of a rockburst disaster in the mine is slim in the short term.
