Research on the Destructional Pattern of Surrounding Rock of Roadway Induced by Dynamic Disturbance

The low frequency strong-dynamic disturbance is one of the sources of deformation and failure of surrounding rock in rockburst roadway, but its deformation and failure mechanism and spectrum characteristics still need further study. In this paper, we selected 4 levels and 5 factors with an orthogona...
