以某深井沿空工作面开采为背景,采用微震监测技术进行现场监测,并借助FLAC3D进行数值分析,研究在采动应力场不断变化过程中采场围岩破裂微震事件的时空演化规律,揭示沿空工作面采动影响范围及冲击危险区域,得到以下结论:沿空工作面沿空一侧覆岩破裂高度最大,约为两采空区短边之和的一半;沿空一侧工作面超前影响范围约为非沿空一侧的2倍;沿空一侧应力集中程度高,存在发生冲击地压的危险。 Based on the mining of a working face in a deep well, the micro-seismic monitoring technique was used to carry out on-site monitoring. The numerical analysis was conducted with FLAC3D to study the spatiotemporal evolution of the microseismic event in the surrounding rock during the continuous mining stress field. The influence range of mining face with empty working face and impacting danger zone are as follows: the height of the overburden rock along the empty working face is the largest, which is about half of the sum of the short sides of two gobs; The influence range is about 2 times of that on the non-empty side; the concentration of stress on the sky side is high, and there is a danger of rock burst.
