摘要
论文通过对黄陵一号煤矿625回风顺槽延伸段临近1001工作面采空区掘进、625切眼临近1001及623工作面采空区掘进施工过程中,遇到的巷道顶帮垮落、收敛等围岩变形破断难题,通过开展有针对性的分析研究,得出巷道变形破坏规律及破坏特点,并对巷道掘进工艺和支护参数进行了优化,取得了较好巷道成型效果。
The paper passes through the roadway roofs encountered during the construction of the goaf of the 625 return airway extension section of Huangling No.1 coal mine near the 1001 working face,and the 625 open cut near the goaf of the 1001 and 623 working faces.For surrounding rock deformation and fracture problems such as collapse and convergence,targeted analysis and research have been carried out,and the rules and characteristics of roadway deformation and failure have been obtained.The roadway excavation technology and support parameters have been optimized,and a good roadway shaping effect has been achieved.
