注浆充填联合锚网喷支护技术在穿层斜巷中的应用

Application of grouting-filling combined with bolt-mesh-shotcrete support in inclined roadway through strata

介绍了在复杂地质条件下,穿层斜巷的施工过程。通过采用注浆充填围岩裂隙,提高围岩自身的承载能力、保持围岩整体稳定性,然后进行锚网喷支护,有效的控制巷道围岩变形,解决了穿层斜巷的支护难题。

The paper introduced the construction process of the inclined roadway through strata in complicated geological conditions. By using grouting-filling and bolt-mesh-shotcrete support,the bearing capacity of surrounding rock was improved,the stability of surrounding rock was maintained,the roadway deformation was effectively controlled and the supporting problem of inclined roadway through strata was solved.
