摘要
采用UDEC数值模拟软件对宽沟煤矿冲击地压与采动应力场的关系进行了研究,揭示了受采动影响下的高应力和高能量场是影响浅部煤层工作面冲击地压发生的主要因素,并通过PASAT-M便携式微震检测系统对采动应力场数值模拟结果进行了验证。
The relationship between rock burst and mining stress field of Kuangou coal mine was studied by UDEC numerical simulation software,the results showed that high stress and high energy field that induced by mining were the main factors,which affected rock burst appeared of working face in shallow coal seam,and also the numerical simulation results of mining stress field was verified by PASAT-M portable microquake detecting system.
