摘　　要：为解决81108工作面回风巷原有支护围岩变形量大的问题,通过现场观测围岩变形特征及过程,得出需提升巷道两帮围岩支护强度。基于巷道原有支护下围岩变形特征,确定巷道采用顶帮协同支护技术,进行支护优化和围岩变形监测分析。结果表明:支护优化方案实施后,沿空掘巷期间围岩变形量大幅降低,保障了围岩的稳定。In order to solve the problem of large deformation of surrounding rock of original support in return air roadway of the 81108 working face,through on-site observation of surrounding rock deformation characteristics and process,it is concluded that it is necessary to improve the supporting strength of surrounding rock of two sides of roadway.Based on the deformation characteristics of surrounding rock under the original support of roadway,it is determined that the roadway adopts roof-slope cooperative support technology to optimize support and monitor and analyze the deformation of surrounding rock.The results show that after the implementation of the support optimization scheme,the deformation of surrounding rock is greatly reduced during roadway driving along goaf,which ensures the stability of surrounding rock.
