Based on RFPA software, the numerical simulation of rock burst in circular roadway is carried out under different horizontal stresses. The paper studies the distribution of stress field, the crack propagation and acoustic emission characteristics in the process of rock burst. The results show that the stress moves and the concentration of compressive stress appears on left and right sides of roadway after excavation of the roadway, and tensile stress zone appears at the top and bottom of the roadway. The shear fracture on the roadway’s left and right sides is more serious. The larger the horizontal stress is, the earlier the energy releases and the higher the total energy is.
