摘　　要：为考察ESG微震监测系统在矿井动力灾害救援中的可用性,借助微震技术的实时定位功能,设计矿井灾害救援模拟测试方案。模拟测试包括多个传感器敲击、单个传感器敲击和单个传感器喊话等3个试验,以此研究该系统接收不同声音信号的最佳距离。结果表明:该系统接收声音信号的清晰程度依次为:敲击锚杆(索)>敲击围岩>敲击管道>喊话,并且在系统接收清晰条件下,采取这4种动作的最佳距离分别是30,20,10和5 m。program sim To study the usability of ESG microseismic monitoring systems in mine disaster rescue, a test ulating mine disaster rescue was designed. The program contained tapping tests with multi-sen- sors, tapping tests with single-sensor, and voicing tests with single-sensor. The optimal distances for differ- ent sound signals to be received by the above system were studied. The results show that for the clarity of signals received by the microseismic system, there is a sequence of tapping anchor 〉 tapping rock 〉 tapping conduit 〉 shouting, and that the optimum distances for respectively. taking the 4 kinds of actions are 30,20,10 and 5 m
