摘　　要：采用FLAC3D数值模拟软件,研究了断层带附近采动影响下支承压力的变化规律。研究认为,随着工作面与断层距离缩小,工作面前方的煤岩体应力集中系数呈现不断上升趋势,冲击危险性也随之增加,当工作面推进至断层带20 m时,必须采取有效的防冲措施达到弱化冲击强度的目的。该研究对附近有断层工作面的采场布置及采掘作业具有参考价值和指导意义。The FLAC^3D numerical simulation research on abutment pressure of variation rule effected by mining of the deep fault zone. The study show that the closer the face between the fault,the stress concentration coefficient of the face show a rising trend,the more risky,must take the necessary measures against erosion in order to weaken the strength when the working face distance the fault zone from 20 m. The study have certain reference value and guiding significance for formulating the anti-shock measures of the working face is nearby fault..
