摘要
For operation roadway of anchor net support with rock burst tendency, the paper analyzed mechanism that anchor of roadway depress disaster of pressure bump by use of dynamic theory and researched influence degree of different anchor parameters on surrounding rock of roadway with rock burst hazard by use of numerical simulation software FLAC3D. The research result showed that main influencing factors of deformation of surrounding rock of roadway are length and distance of anchor bolt, sensitivity for anchor parameters of deformation of roadside is higher than roof and bottom of roadway.
