【摘要】 用模型试验研究裂隙岩体巷道稳定性规律,分析了裂隙间距、裂隙倾角及其裂隙方位和巷道轴向夹角等因素对巷道围岩收敛变形的影响,提出了有利于巷道稳定与维护的轴向布置总体选择原则。更多还原

【Abstract】 Draft stability rule is studied through model test,inf lu ences of distance between froctures(I),fracture inclined angel(φ),and the angel between draft and facture on surrounding rock deformation are analysed,a draft layout principle that is helpful to draft stability is put foreward.更多还原
