鲁西南某煤矿地应力实测结果表明最大水平应力方向与工作面巷道夹角一般在40o~70o左右，最大水平应力对巷道稳定性影响较大。为保证矿井安全生产，在不改变采区设计情况下，基于地应力实测结果采用大型岩土类三维分析软件3D-FSM·DDM间接边界元数值系统探求原岩应力与锚杆支护强度的关系，为巷道支护优化提供科学依据。

A coal mine in Southwest Shandong Province stress test results show that the angle of the maximum horizontal stress direction and working face roadway is general 40 degrees to 70 degrees or so, the inlfuence the maximum horizontal stress on the stability of roadway is larger. In order to ensure the safety in production of coal mine, without changing the design of mining area condition, based on the in-situ stress measurement results, using the original rock of large-scale geotechnical three-dimensional analysis software 3D-FSM-DDM indirect boundary element numerical system explored the relationship between stress and strength of bolt support, and provided the scientiifc basis for the optimization of roadway support.
