软岩巷道破坏机理的研究

his paper analyzes the characteristics of soft rock roadway, combined with practical application, designed to spray a new anchor shell supporting structure and proposed mechanism of interaction with the rock that anchors the shell surrounding rock and shotcrete support system as an entity, anchor-body system and the deep rock formation deep rock control systems, housing systems and the formation of shallow shallow rock rock control system, through the bolt will be deep and shallow rock together, spray-body system play a three-dimensional constraints on the rock role, while reinforcing the shell system, through the anchor body system and the housing system of flexible scalability to adapt to large deformation of soft rock roadway
