Abstract: Taking Yima mining area as the background, the simplified numerical model of thrust fault is established with FLAC^3D which has the strong numerical simulation ability. The distribution law is studied that the abutment pressure and elastic energy of the working face under different fault dip condition. The research results show that the abutment pressure of working face remarkably increases with the mining face constantly close to the fault. The abutment pressure peak of working face will increase with the fault dips increasing when the distance from the working face to the fault is 40 m and the fault dip is less than 45°. Moreover, the abutment pressure peak of working face will be decrease with the fault dips increasing when the fault dip is more than 45°. Meanwhile, the energy peak is minimum when the fault dip is 30°, and the energy peak is maximum when the fault dip is 45°.
