Abstract: In order to study the stress-displacement evolution law of surrounding rock in fully mechanized caving face in graben area, based on the geological conditions of 1313 working face in graben area of Xinglongzhuang Coal Mine, a mechanical model was constructed to analyze the activation mechanism of graben structure.It is concluded that the minimum critical value of fault activation（σ₁-σ₃） is positively correlated with the fault friction angle φ cohesion c and the minimum principal stress σ3.Through FLAC3 D numerical simulation, the stress-displacement evolution law of surrounding rock of 1313 working face in graben area is studied, and the key areas of mine pressure prevention and control are obtained.The energy-induced blasting scheme of Guanzhuang No.2 fault was proposed and verified on site.The results show that when the working face roadway is 20～40 m away from the fault structure, the mining stress field and the tectonic stress field are obviously superimposed.When the working face is 20 m away from the fault, the superposition effect reaches the maximum, the peak stress is about 36 MPa, and the maximum convergence of the two sides of the roadway surrounding rock is 560 mm.After the treatment of induced energy blasting, the energy and frequency of microseismic events on the side of the transportation gateway are reduced with the obvious effect of induced energy blasting.
