摘　　要：采空区已成为影响矿山安全生产的主要危害因素之一,对其进行实时监测是防范采空区灾害事故发生的重要手段,也是进行采空区稳定性研究的主要方法。为了监测预测采空区灾害事故,潘洛铁矿建立了微震监测系统,通过对三种不同布置方案定位精度与敏感度的对比与分析,合理优化了传感器台网布置,并在现场采用人工爆破的方法对系统性能进行了测试。结合现场实际,分析总结了微震事件在时间、空间上的分布,监测效果明显,对于防范采空区灾害有一定的参考价值。Goaf has become one of main risk factors for safety in production of mines.The real-time monitoring of goaf is an important mean to prevent the disaster, and also is a main method to research stability of goaf.In order to monitor and forecast goal disaster, a microseismic monitoring system has been built in Pan- luo iron mine. By analyzing and comparing the positioning accu- racy and sensitivity of three different layout modes, the layout of sensors network was optimized, and the system performance was tested by the method of artificial explosion on site. According to the site monitoring data, the distribution of microseismic events in time and space were analyzed.The monitored results were ob- vious, which was of a certain reference value to the prevention of goaf disaster.
