摘　　要：针对工作面“见方”期间微震大能量事件的监测与解危措施进行了深入研究。通过对微震数据的实时监测和分析,揭示了微震大能量事件的发生规律和特征,并提出了有效的解危措施。结果表明:微震大能量事件在工作面“见方”期间具有较高的发生概率,一次“见方”时微震事件能量主要集中在B1、下煤层范围内,煤层上方顶板能量事件相对较少,且微震能量事件基本在工作面上方110 m,在此阶段开采能量事件较为平稳。通过实施相应的解危措施,可以有效降低微震大能量事件的影响,保障采矿作业安全顺利进行,并为采矿工程地震灾害防范提供有益参考,有助于提高采矿作业的安全性和稳定性。This paper conducts an in-depth study on the monitoring and risk relief measures of large energy microseismic events during the“square”formation at the working surface.Through the real-time monitoring and analysis of microseismic data,the study reveals the occurrence laws and characteristics of large energy microseismic events,and proposes effective measures.The research results show that large energy microseis⁃mic events have a high probability of occurrence during the“square”formation at the working surface.The energy of microseismic events is mainly concentrated in the B1 and lower coal seams during a“square”for⁃mation.The energy events of the upper coal seam roof occur scarcely.The microseismic energy events basi⁃cally occur within the range of 110 m above the working surface,so the mining energy events are relatively stable at this stage.The implementation of the corresponding risk relief measures makes it possible to reduce the impact of large energy microseismic events effectively,ensuring safe and smooth progress of mining opera⁃tions.This study provides valuable references for the prevention of earthquake disasters in mining engineering and helps to improve the safety and stability in mining operations.
