摘要
为了提高冲击地压矿井微震监测系统的监测精确性和可靠性,本文通过对比同时间、同区域回采期间,煤层及上覆岩层内产生的能量事件频次、释放总能量和上覆岩层中微震事件分布规律,结合顶板取芯柱状图,从多个角度对两套微震监测系统进行对比分析,为今后矿井微震监测设备选型提供有力依据。
In order to improve the monitoring accuracy and reliability of the microseismic monitoring system in rock burst mine,this paper compares the frequency of energy events generated in coal seam and overlying strata,the total energy released and the distribution law of microseismic events in overlying strata during the same mining period at the same time and in the same area.Combined with the core taking column diagram of roof,the comparison and analysis of the two sets of microseismic monitoring systems from multiple angles provides a strong basis for the selection of mine microseismic monitoring equipment in the future.
