摘　　要：石嘴山一矿38区+600m轨道巷的稳定情况是影响矿井下组煤正常生产的潜在问题,本文基于岩石力学实验与现场工程调查的结果,对该巷道变形机理与破坏过程及规律进行固-流耦合数值模拟分析,得出注浆锚杆(索)与喷射混凝土联合支护方式是可行的,为巷道支护设计提供了理论依据。The stability of the haulage tunnel at the ＋ 600m level was a potential problem in Shizuishan coal mine. Based on the test of mechanical properties of surrounding rocks and underground pressure inspection,analyses mechanism of roadway deformation and large deformation rules through the couple of solid- fluid numerical simulation, concluding that the blot-inject and bolt-shotcrete combined support method is feasible, and provide the theory support for supporting design.
