紅慶梁煤礦軟巖巷道穿越斷層破碎帶加固支護技術(shù)
[Abstract]:Fault geological hazard is one of the important problems in soft rock roadway construction. Taking the soft rock roadway of Hongqingliang coal mine as the research object, the fracture characteristics of soft rock roadway in Hongqingliang coal mine are determined by the advanced geological prediction, and the failure mechanism of the surrounding rock of the fault is deeply studied. This paper puts forward the comprehensive reinforcement and support technology of "pre-grouting variable cross section advance pipe shed 'anchor, mesh and cable spray frame respray'". FLAC~ (3D) is used to simulate the deformation characteristics of surrounding rock and the stress of supporting structure in soft rock roadway, which verifies the feasibility of the comprehensive reinforcement and support technology. The monitoring results in engineering practice show that the reinforcement and supporting effect is good and the safety and stability of soft rock roadway with fault are guaranteed. This innovative achievement directly guides Hongqingliang Coal Mine to successfully cross dozens of faults and provides a reference for the construction of the west mine to cross the fault fracture zone.
