Rockburst disaster caused by the superimposed action of strong dynamic load and high concentrated static load formed by mining in the mining process of working face with complex geological conditions and mining conditions. This paper takes the 7302 irregular working face of Zhaolou Coal Mine as the research object, through on-site sampling test, impact risk assessment, theoretical analysis, refined numerical simulation, multi-parameter monitoring and warning, and prevention and control collaborative control technology, etc, The mechanism and prevention of mining induced impact of irregular working faces in the area affected by complex fault structures are studied. The results show that the shear modulus of the weak plane of the fault is in direct proportion to the shear stress required for sliding instability. When the consistency of the failure strength of the bond point on the weak plane of the fault is high, it will produce an instantaneous stress drop in the state of stick-slip friction and induce a strong mine earthquake; When the the working face width is large, the thick and hard layer in the middle and high level of the overburden is more likely to reach the limit breaking distance and break, resulting in strong dynamic load disturbance, at the same time, the static load stress concentration and range in the surrounding rock of the mining space are increased; The refined three-dimensional numerical simulation has determined the potential impact risk area, and pointed out that the mining has disturbed the Fz14 reverse fault and Fd64 normal fault, which led to its activation; Multi-parameter spatial quantitative technology can identify and monitor precursors during mining in real time, and can timely feedback the effectiveness of prevention and control collaborative control technology
