摘要： 由于1523101 巷支护时间长、围岩松软，巷道断面仅为原断面的30%，不能满足后续使用需要。在分析巷道
围岩变形量过大原因的基础上，提出采用以注浆+ 预应力锚杆、锚索为核心的巷道加固技术，并进行现场应用。结果表
明，在加固巷道围岩后，巷道底板、巷帮位移量显著降低，加固后的巷道可满足后续使用需要。

Abstract: Due to the long support time and loose and soft surrounding rock of 1523101 roadway, the roadway section is only 30%
of the original section, which cannot meet the needs of subsequent use. Based on the analysis of the reason for the excessive
deformation of the surrounding rock of the roadway, it was proposed to adopt the roadway reinforcement technology with grouting +
prestressed bolts and anchor cables as the core, which was applied on site. The results show that after the surrounding rock of the
roadway was reinforced, the displacement of the roadway floor and sidewall was significantly reduced, and the reinforced roadway
can meet the needs of subsequent use.
