中文摘要：
在井下巷道工程设计多个微震监测系统传感器站网空间布置方案,地震信号由传感器采集并进行前置放大,传至井下数据交换中心,经A/D转化后的数字信号再经由光缆传至地表监测控制中心相连的计算机,利用监测数据对矿山地震活动及岩爆与地压活动进行分析研究、实时的监测和预报。应用该微震监测技术对冬瓜山铜矿的事件定位精度和系统灵敏度的分析,对人工震源定位及定位精度进行的验证实验以及对冬瓜山矿区井下各种振动波形进行的识别和分析,取得了很好的效果。微震监测系统的建立对于推动我国矿山地压灾害监测和安全管理水平具有重要参考意义。
英文摘要：
Space collocation scheme about Multi-micro-seismic Monitoring System sensor station net is designed in well laneway project in this paper.In this system,the earthquake signal is firstly gathered and magnified by sensors,and then sent to data exchange center under well through cable.After transformed into digital signals through A/D,it is then sent to the computer connected with the control center on ground surface through cable.The monitoring data can be used to analyze and forecast the mine earthquake activity,rock-burst and underground pressure activity timely.This micro-seismic monitoring technique is applied to the analysis on the precision of incident orientation and system sensitivity,the verification of the location precision of vibration source and the identification of vibration waves in Dongguashan Copper Mine.The result is quite good.This system is favorable to the improvement of hazard monitoring and safety management for Chinese mines.
