某矿过断层石门工程的数值模拟研究

Based on in-situ stress measuring results in a coal mine, three kinds of crossway geological model have been established by FLAC 3D numerical simulation. It is concluded that the best solution is selecting location, No.1 level and the orientation of maximum principal stress is the crossway's move towards. It's better to avoid stress concentration phenomenon appeared and support roadway easily. According to the actual project, selecting the location between -450 and -550 m and determining crossway is between 02 and 03 exploration line. Finally it puts forward suggestions on construction, support and waterproof.
