摘　　要：根据田陈煤矿微震监测系统的监测结果,分析了工作面推进速度、断层、向斜及刀把型煤柱对微震活动的影响,结果表明:微震活动频次与推进度成正相关,推进度的剧烈变化会导致大能量事件的增多;7110工作面微震事件的分布受断层等构造影响较大。通过对微震能量分布的分析划定了高冲击危险区域,进而对田陈煤矿冲击地压的防治提供了依据。On the basis of observation data from micro-seismic monitoring in Tianchen Colliery , the influence of mining speed , fault, syncline and hilt-shape coal-pillar on micro-seismic was analyzed.Results showed that micro-seismic number was positive correlated with mining speed and large mining speed variation could result into increasing of matters with large -energy.Micro-seismic matters dis-tribution of 7110 mining face was influenced mainly by fault tectonic .By analyzing micro-seismic energy distribution , high rock-burst danger region was obtained , which provided reference for rock-burst prevention in Tianchen Colliery .
