摘要：
Based on the feature of roadway surrounding rock with fractured roof, the influencing factors on the stability of roadway surrounding rock with fractured roof were analyzed. It was found that the main controlling factors affecting the deformation and failure of roadway surrounding rock with fractured roof are ground stress, roof strength and joint properties. Thus, numerical software UDEC was used to investigate these factors on the stability of roadway surrounding rock. Numerical results indicate that the greater the ground stress, the greater the roadway deformation. The weaker the roof strength, the larger the roadway deformation range. Roadway deformation increases rapidly with decreased joint properties.
