Based on the analysis of distribution characteristics of initial rock stress observed at -300 m level of No.6 colliery of Hebi, the regionalinitial rock stress field is simulated by applying displacement discontinuity method and iteration calculating method. The influence of complex faults on the initial rock stress status is inquired through analyzing the distribution characteristics of maximum and minimum horizontal stresses. In addition, influence of faults on the stability of underground opening and gas extrusive is discussed by comparing the regional characteristics of ground pressure with ones of initial rock stress. It is shown that regional distribution characteristics of stress field depends upon the superposition of complex faults. And then, it causes notable regional difference of stability of underground openings and gas sudden extrusive.
