砚北煤矿矿震分布规律及其影响因素分析

Distribution regularity and influencing factors of mine quake in Yanbei Coal Mine

开采活动中主要影响因素包括顶板来压、煤柱失稳和工作面上方覆岩运动等。以砚北煤矿2502采区为研究对象,利用SOS微震监测系统对2502采区回采过程中强矿震位置进行监测并分析得到砚北煤矿强矿震显现不是单一因素导致,而是地质和开采技术因素相互叠加共同导致的结果,其中开采技术因素占主导地位。

The main factors affecting mining activities include roof weighting, pillar instability and overburden movement above the working face. Taking 2502 mining area in Yanbei Coal Mineas the research object, using SOS microseismic monitoring system to monitor and analyze the location of strong earthquake in the mining process of 2502 mining area,.It was concluded that the occurrence of strong earthquake in Yanbei Coal Mine is not caused by a single factor, but by the combination of geological and mining technology factors, among which mining technology factors are dominant.
