通过对张小楼千米深井主要开拓巷道变形破坏原因分析 ,提出了控制深部巷道变形的有效措施 ,即选择合理的支护形式 ,控制围岩流变 ;改善围岩力学性质 ,充分发挥围岩自稳能力 ;先“柔”后“刚” ,二次支护。
Based on the analysis of the causes of the deformation and failure of the main open roadway in the 1000m deep shaft of Zhang Xiaolou, the effective measures to control the deformation of the deep roadway are put forward, that is, the reasonable support forms are selected to control the rheology of the surrounding rock; the mechanical properties of the surrounding rock are improved; Self-stabilization ability; first “soft” after “just”, secondary support.
