摘　　要：通过理论计算和FLAC3D数值模拟,并考虑到实际围岩条件,提出了合理有效的巷道锚杆和锚索支护参数。经过现场试验验证,新支护参数能有效地提高巷道支护强度,加快巷道掘进进度,保证巷道安全稳固,同时为安居煤矿其他工作面巷道支护施工提供了借鉴。Reasonable and effective support parameters of bolts and anchor cables are proposed by theory calculation and FLAC3 Dnumeric simulation,considering actual condition of surrounding rock.Through the field test confirms,new support parameters can improve the support strength of the roadway effectively,accelerate the driving progress of the roadway and guarantee safety and security of the roadway,meanwhile,the technology provide a reference for the construction of other roadways on Anju mine.

关 键 词：支护参数 理论计算 数值模拟 巷道支护
