Abstract
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.关键词
