为解决阳城煤矿-650南翼轨道大巷断层破碎带支护中出现的围岩变形大和变形持续时间长等问题，采用室内实验、理论计算和支护实践相结合的方法，对-650南翼轨道大巷围岩地质进行测试研究，揭示巷道原有支护变形破坏机制，提出断层破碎带巷道承压环强化支护设计方法，并由此设计基于钢管混凝土支架的复合支护设计方案。实验及理论分析得出： 钢管混凝土支架支护反力为0.92 MPa，基于钢管混凝土支架的复合支护体总体承载力达到1.37 MPa，超过预估围岩压力。支护实践表明： 基于194 mm×8 mm浅底拱圆形钢管混凝土支架复合支护方案能够有效控制巷道变形，抑制底鼓，保证了-650南翼轨道大巷的长期稳定。

Large surrounding rock deformation occurs in support of fault and fracture zone of -650 south tunnel of Yangcheng Coal Mine; and the deformation lasts for a long time. As a result, the surrounding rock geology of -650 south tunnel is tested and studied by indoor experiment, theoretical calculation and support practice; the deformation failure mechanism of the original tunnel support is revealed; the design method for pressurebearing ring support strengthening is put forward; and the composite support method based on concretefilled steel tubular scaffold is designed. The theoretical analysis and experiment show that the counterforce of concretefilled steel tubular scaffold reaches 0.92 MPa and the bearing capacity of composite support based on concretefilled steel tubular scaffold reaches 1.37 MPa, which has exceeded the predicted surrounding rock pressure. The support practice shows that the tunnel deformation can be effectively controlled and the longterm stability of -650 south tunnel can be guaranteed by using composite support based on 194×8 shallow arch concretefilled steel tubular scaffold.
