以新景矿80116综放工作面回风巷为背景,运用FLAC~(3D)软件分析巷道围岩变形破坏特征,研究了中空锚索注浆加固机理,设计了锚注加固支护方案并进行了工程应用,有效控制了巷道的围岩变形。
Based on the air return tunnel of the 80116 fully mechanized caving face in Xinjing Mine, FLAC 3D software is used to analyze the deformation and failure characteristics of roadway surrounding rock. The grouting reinforcement mechanism of hollow anchor cable is studied. The engineering application, effectively control the deformation of the surrounding rock roadway.
