| Abstract: | In order to support the roadway effectively，this paper studied the stability of the roadway with high-strength bolt grouting support，to analyzethe high-strength bolt grouting support system，mainly to analyze the new hollow grouting anchor cable，hollow grouting bolt，cement grouting additive and construction equipment.By using FLAC3D numerical simulation software，the plastic zone and stress distribution under different anchoring and grouting conditions were analyzed，and field tests were carried out.The results showed that high strength bolt grouting supporting can effectively control the surrounding rock of roadway. |
