| Abstract: | Taking one mine as engineering background of the research,according to the distribution characteristic of initial rock stress measurements,the complex structural rock stress field was simulated by means of establishing numerical model being suited to behaviors of rock and applying displacement discontinuity method.The influence of complex faults on colliery regional initial rock stress was inquired through DDM(Displacement Discontinuity Method) numerical calculating.It is shown that the distribution of regional initial rock stress of colliery depends upon the faults and the aeolotropium of distribution of initial rock stress is formed because of superposition of the action of faults. |

| Keywords: | colliery initial rock stress field in suit measuring influence of faults numerical analysis |
