Influence of Rock Burst and Other Disasters on Stability of Surrounding Rock of Roadway

Abstract In this paper, selecting 3 levels and 6 factors with an orthogonal test approach to investigate the stability of roadway surrounding rock under dynamic disturbance. The intuitive analysis results show that the main factors that affect the roadway deformation is period, followed by the location, lateral pressure coefficient, amplitude and buried depth,while the elastic modulus has a relatively small effect on it. With the increase of amplitude, period, depth and lateral pressure coefficient, the deformation of the roadway intensifies. With the increase of elastic modulus, the roadway deformation is first increases and then decreases. The farther the focal position, the smaller the roadway deformation. Combined with the engineering geological conditions of No. 11 Mine, using the micro-seismic monitoring curve to simulate the surrounding rock stability of No. 21222 interconnection, results show that the amplitude gradually decreases with the increase of the distance from the source.
