摘　　要：针对ARAMIS M/E井下微震监测系统在垂直层位上定位精度较差问题,构建一种ARP 2000 P/E+ARAMIS M/E一体化联合监测系统,对2022年3月期间1550个有效微震事件在垂直方向上分布特征及数量特性进行分析,深入研究微震事件分布规律与导水断裂带发育高度之间的关系。结果表明:微震事件在平面上主要集中在工作面两端,且垂直方向上主要分布在煤层顶板至上方80 m内,与导水断裂带的发育高度紧密相关。联合监测系统获得的定位结果与覆岩“三带”现场实测结果高度一致,证实该联合监测系统在震源垂直定位精度上的有效性,ARP 2000 P/E+ARAMIS M/E一体化联合监测系统可为矿井防治水提供一种有效的技术手段。In view of the problem of poor positioning accuracy of the ARAMIS M/E downhole microseismic monitoring system in vertical layers,an ARP 2000 P/E+ARAMIS M/E integrated joint monitoring system is constructed.The distribution characteristics in vertical direction and quantity characteristics of 1550 effective microseismic events during March 2022 are analyzed,and the relationship between the distribution law of microseismic events and the development height of water conducting fractured zones is deeply studied.The results show that microseismic events are mainly concentrated at both ends of the working face in the flat surface,and are mainly distributed within 80 m above the coal seam roof in the vertical direction,closely related to the development height of water conducting fractured zones.The positioning results obtained by the joint monitoring system are highly consistent with the on-site measurement results of the"three zones"of the overlying rock,confirming the effectiveness of the joint monitoring system in the vertical positioning accuracy of the seismic source.The ARP 2000 P/E+ARAMIS M/E integrated joint monitoring system can provide an effective technical means for mine water prevention and control.
