To explore the influence of different mining sequences on the fault stability

this paper put forward the hypothesis of stress rotation based on pressure arch theory. Firstly

a numerical model was set up to simulate the process of working face passing through the fault from the hanging wall and footwall to the fault. And then it analyzed the stress state and evolution law of contact surface

and verified the stress rotation induced by mining. Finally

comparative analysis of the fault damage variables and their growth rates was carried in this paper. The results show that during the propulsion process of working face from different directions of hanging wall and footwall of fault

the distance between start position of principal stress rotation in roof and fault is 120 m and 40 m

respectively. The maximum value of principal stress deflection angle when the working face located at footwall is 1.68 times than the value when located at hanging wall. The starting slip points of fault damage variables are 130 m and 40 m from fault

respectively. The fine correspondence between them indicates that stress rotation is significantly related to fault slip instability. The caption of additional stress induced by stress rotation can well explain the difference of fault stability due to different mining sequences

and provide new ideas for the design of fault coal pillar and disaster prevention measures.
