摘要
根据集贤煤矿微震事件的监测结果,从微震事件的能量分布、空间位置分布、与工作面推进和组织生产的关系等方面,对微震事件的发生规律和分布特征进行了分析,得出冲击地压发生前的微震活动特征及微震事件能量与冲击地压的关系,并对高冲击危险区域进行了判定,进而对集贤煤矿的冲击地压灾害的防治提出了建议,为冲击地压灾害的防治提供了依据。
Based on the monitoring results of microseismic incidents in Jixian Coal Mine, analysis was made on the occurrence regularity and distribution characteristics of the microseismic incidents from the aspects of the energy distribution, space and position distribution of the microseismic incidents and the relationship with the face advance and production organization. The characteristics of microseismic activity before the occurrence of the rock burst and the relationship between energy of microseismic incidents and rock burst were obtained. The areas with high tendency of rock burst were determined and suggestions for the prevention and control of rock burst in Jixian Mine were put forward, all of these provided the basis for the prevention and control of rock burst.
