摘　　要：随着开采深度的不断增加,矿山地压问题逐渐显现。玲珑金矿大开头矿区地质构造复杂且开采深度远大于理论岩爆发生深度,故在该矿区建立微震监测系统,将微震监测技术作为地压监测及灾害预警手段。大开头矿区岩心取样结果表明,该区域内有很大概率发生岩爆灾害。利用微震监测系统对微震事件时空分布规律和灾害前兆特征b值、H指数进行分析,并与矿区岩爆记录相对应,验证微震监测技术在深井灾害预警中的可行性。With the increase of mining depth,the mine ground pressure problem gradually appears.The geological structure of Dakaitou mining area of Linglong Gold Mine is complex and the mining depth is much larger than the theoretical rockburst depth.Therefore,a microseismic monitoring system is estab⁃lished in the mining area,and the microseismic monitoring technology is used as a means of ground pres⁃sure monitoring and disaster warning.The core sampling results of Dakaitou mining area show that there is a great probability of rockburst disaster in this area.The microseismic monitoring system was used to analyze the temporal and spatial distribution of microseismic events,the b value and H index of disaster precursor characteristics,which corresponded to the rockburst records in the mining area to verify the feasibility of microseismic monitoring technology in the early warning of deep well disasters.
