| Abstract: | The deformation characteristics and control technology of surrounding rock in deep roadway with high stress were analyzed.The variation law of vertical displacement and the expansion law of plastic zone of surrounding rock were analyzed by FLAC3D numerical simulation software.According to the deformation characteristics of surrounding rock in deep roadway with high stress，the coupling support system with bolt grouting as the main support method was designed，and the improved support mode was verified.The results showed that the deformation of surrounding rock can be effectively controlled by the coupling support scheme of bolt grouting and high strength prestressed bolt. |
