| Abstract: | Aiming at the problems of roadway rock fragmentation and serious bolt failure,taking 13102 roadway as the engineering background,the broken features of the roadway under the existing support scheme were summarized,the reasons for the serious rock fragmentation were analyzed,the secondary grouting scheme to control the surrounding rock of roadway was put forward,and the grouting parameters were determined.It has been verified through engineering practice,and it is concluded that the secondary grouting scheme can effectively control the deformation and deformation rate of the surrounding rock of the roadway. |
