Abstract: The 11506 fully-mechanized coal face, located at the level of -680 m in Renjiazhuang Coal Mine, advances in the hanging side of the normal fault F₂₅. This research adopts 3D calculation model, ABAQUS, to simulate the effect of faults on the maximum principal stress and roadway displacements ahead of the coal face when it approaches to the faults. In addition, the specific fractured conditions of the overlying strata near the faults are analyzed theoretically in conjunction with in-situ monitoring. The practices indicate that the positions where the overlying strata fracture can be interrupted by the fault as the 11506 coal face advances in the normal fault hanging side. This type of effect is especially severe when the coal face is near to or passing through the fault . In comparison to the normal condition, the roadway displacement near the fault is 10 to 20 cm higher and the stress in the rib bolts is 2 to 4 MPa greater.
