摘 要:为保障11-104回风顺槽复合软弱顶板围岩的稳定,通过分析复合软弱顶板破坏机理,基于顶板协同支护控制思路,结合回风顺槽的具体特征,进行顶板和两帮锚杆索各项支护参数的设计,并在巷道掘进期间进行巷道围岩变形量的监测分析。结果表明:支护方案实施后,巷道掘进期间围岩变形量较低,围岩处于稳定状态。In order to ensure the stability of the surrounding rock of the 11-104 return air trench compound weak roof,through the analysis of the failure mechanism of the compound weak roof,based on the idea of roof cooperative support control,combined with the specific characteristics of the return air trough,the supporting parameters of the roof and two sides of anchor cables are designed,the deformation of roadway surrounding rock is monitored and analyzed during roadway excavation.The results show that after the implementation of the support scheme,the deformation of surrounding rock is low and the surrounding rock is in a stable state during roadway excavation.
