摘要
在分析埋深和巷宽对深部巷道围岩变形的影响规律后,结合现代支护理论和高强材料特性,提出采用高强度、高韧性锚网索耦合协调支护工艺来控制深部顺槽大断面巷道大变形的设想,对宁东矿区未来深部开拓巷道的支护工艺提供借鉴意义。
In the analysis of burial depth and width on the influence law of deep roadway surrounding rock deformation, combined with modern support theory and high strength material properties, the high strength, high toughness of bolt mesh cable coupling support technology to control deep groove along the idea of large deformation of roadway, not to the deep development of reform roadway support technology to provide reference.
