摘　　要：为实时掌握栖霞山铅锌矿井下主要区段地压变化及地压转移情况,建立1套12通道微震监测系统,对开采过程中的微震事件进行监测,根据监测数据分析监测区域内地压显现规律,并对潜在的安全生产风险做出评估。实践表明:在考虑作业扰动因素时,采场微震监测系统预警显示地压活动达到“活跃”等级;此外,地压活动较稳定,未达到分级预警限值。基于微震监测的地压活动预警系统具有一定实用性和准确性,下一步将考虑采区的变化而优化系统布置范围。In order to grasp the change of ground pressure and the transfer of ground pressure in the main section of Qixiashan Lead-zinc Mine in real time,a 12-channel microseismic monitoring system was established to monitor the microseismic events in the mining process.According to the monitoring data,the law of ground pressure in the monitoring area is analyzed,and the potential safety production risk is evaluated.The practice shows that when the disturbance factors of the operation are considered,the early warning of the microseismic monitoring system in the stope shows that the ground pressure activity reaches the'active'level.In addition,the ground pressure activity is relatively stable and does not reach the early warning limit.The ground pressure activity early warning system based on microseismic monitoring has certain practicability and accuracy.In the next step,the system layout range will be optimized considering the change of mining area.
