Most of the coal and gas outburst sites occur near normal faults tectonic zone. In this paper, the evolution law of stress field and displacement field of driving face under different tectonic zone width of the normal fault was studied, and the support body model of normal fault coal and gas outburst was constructed, the occurrence mechanism of normal fault coal and gas outburst was revealed, and the prevention and control strategy of normal fault coal and gas outburst was put forwarded. The results show that the greater the width of the fault tectonic zone, the higher the horizontal stress of the driving face, the greater the deformation degree, and the higher the risk of coal and gas outburst. Based on the support body model, the criterion of coal and gas outburst induced by disturbance of normal fault is proposed, and the evolution process of coal and gas outburst from start to end of normal fault is revealed. Using the microseismic and electromagnetic radiation to monitor the normal fault area, it is found that the fracture frequency and stress of coal rock in the normal fault area are significantly higher than those in the non-fault area, and the stress of fault hanging wall is higher than that of fault footwall. The prevention and control of coal and gas outburst in normal fault tectonic zone should be started from two aspects: eliminating the energy storage body and improving the supporting ability of tectonic zone. The research results provide a new strategy for the prevention and control of coal and gas outburst in fault zones.
