Abstract the stress state of roadway surrounding rock is often quasi dynamic, which is usually subjected to static–dynamic loads. the aim of this study was to investigate the damage process and mechanisms of roadway surrounding rock under com bined static–dynamic loads. This study presents a comprehensive numerical analysis of dynamic rupture and fault induced seismic risks in deep roadway excavation environments, focusing on near fault conditions. With the increase in mining depth, the energy and incidence of microseismic events increase significantly, showing characteristics of zoning and grading along the strike. therefore, the damage to the underground roadway of the wudong coal seam was studied with a focus on dynamic load disturbance. The impact of dynamic disturbance on the deformation and failure of the roadway surrounding rock was studied from a single factor perspective using numerical simulation software.
