Abstract: Under the complex roof condition, the 103-06 lower working face of Baodian Coal Mine has the risk of rock burst, which is prejudicial to the normal production. Aiming at the impact problem of the 103-06 lower working face, the influence of natural factors and technical factors on the rock burst is analyzed at first, and it is concluded that the re-movement of roof and the overburden rock in the upper goaf are the main inducing factors. Then, PFC is used to simulate the specific impact mechanism of overburden strata migration on rock burst. The simulation results show that after the mining of upper and lower coal seams are completed, the interlayer rock mass is damaged to a high degree, and a large amount of accumulated elastic energy can be released. However, the mid-sandstone (17.21 m) and siltstone (11.45 m) in the upper coal seam have not been collapsed, and the re-movement of the strata in the upper goaf has laid a safety hazard for the next extraction. Finally, based on the impact-induced mechanism of the working face lower 103-06, the corresponding risk prevention and control system is established.
