为解决曲江矿西二进风石门巷道拱顶下沉、底部鼓起等变形问题,研究设计了一种新型中空锚索注浆加固方案,通过该方案的实施效果发现:中空锚索注浆可以改变围岩内部松散结构,对围岩起到胶结加固的作用;中空注浆锚索加固技术能够有效控制围岩巷道的变形,保证了围岩巷道的长期稳定性。
In order to solve the problem of deformation such as vault sinking and bulging at the bottom of Shimen gateway in Qujiang mine, a new hollow anchor grouting reinforcement scheme was researched and designed. Through the implementation of this scheme, it was found that hollow anchor grouting Which can change the loose structure inside the surrounding rock and play the role of cementation and reinforcement of the surrounding rock. The hollow grouting and anchor cable reinforcement technology can effectively control the deformation of the surrounding rock roadway and ensure the long-term stability of the surrounding rock roadway.
