注浆锚索在司马矿大变形煤巷中的应用

Application of Grouting Anchored-cable in Large-deformation Coal Roadway of Sima Colliery

  • 摘要: 通过分析研究司马矿二采区猴车巷在采动影响下围岩变形破坏机理,采用中空注浆锚索补强加固巷道顶板的大变形破坏,分析了中空锚索注浆加固机理,设计和实施了支护加固方案,并根据现场矿压观测对支护效果进行了评价,可为类似工程提供经验。

     

    Abstract: Hollow grunting anchored cable was applied to reinforcing roof supporting after analyzing surrounding rock deformation and damage mechanism of aerial passenger roadway influenced by mining.Reinforcement mechanism of hollow grunting anchored cable was introduced.Reinforcement supporting project was carried out and supporting effect was evaluated by on-the-spot observation.This would provide experience for similar engineering.
