摘要
为解决鸿发煤业副井马头门变形破坏问题,根据实际揭露工程条件及马头门变形情况,对马头门的变形原因进行分析,采取了"锚索簇+双液注浆加固"修复方案,现场实践表明,该方案有效地控制了围岩变形,解决了鸿发煤业马头门变形问题,为类似条件马头门支护和变形修复提供了参考、借鉴经验。
Aiming at the deformation and failure of auxiliary shaft ingate of Hongfa coal mine,according to the actual conditions and the ingate deformation,and analysis on deformation reasons,the design use the cable ＂cluster ＋ double liquid grouting＂repair program. Practice has proved that,the surrounding rock deformation is controlled,and the ingate deformation problem in Hongfa mine is solved.
