深部巷道围岩耦合支护原理及其应用分析

Because of complex engineering geological conditions and specific rock structure, deep roadway supporting become more difficult, there is large deformation mainly caused by mesh-anchor of supporting systems and rock deformation are non-coupled. The successfull of deep roadway design, it should be coupled with supporting design philosophy that emphasizes the adaptability between geological conditions and rock-mesh-anchor supporting, so that supporting and deformation are unity. In this paper, coupling support in several key technical issues are detailed analyed which is important in deep roadway supporting.
