摘要
水峪矿面临较为典型的深部巷道支护难题,针对10219运输平巷围岩控制难题,通过分析深井地应力特征及围岩变形破坏特征,确定了巷道的支护原则及具体的锚网索协同支护方案,经掘进支护工程实践及矿压观测验证,设计的锚网索协同支护方案较好地适应了巷道条件,能够保障巷道围岩稳定。
Shuiyu mine is faced with the typical supporting problem of deep roadway. In view of the control problem of surrounding rock of 10219 haulage roadway, firstly, the characteristics of in-situ stress and deformation and failure of surrounding rock are analyzed, then, the supporting principle of the roadway and the cooperative support scheme with bolt-mesh-cable are determined. Through the practice of driving support engineering and the observation and verification of ground pressure, the designed bolt-mesh-cable cooperative support scheme is well adapted to the tunnel conditions, which can ensure the stability of roadway surrounding rock and safe production, and the economic benefit is remarkable.
