摘　　要：以晋煤集团赵庄煤业大采高工作面巷道(53202巷)为研究对象,针对在相邻工作面回采条件下进行巷道掘进的工程特点,对巷道合理支护方式及应用效果开展研究,设计了"锚、网、索、注"巷道联合支护方案,巷间保护煤柱宽度由50m减少至25m。巷道在其服务期间两帮移近量最大值为805mm,顶底板移近量最大值为880mm,顶板下沉量最大值为150mm,能够满足后续工作面的回采需求,为留设保护煤柱、提高资源回收利用率等问题提供了理论依据。Taking the working face with the large mining height in the53202roadway of Zhaozhuang Coal Mine ofJincheng Mining Group as the research object,aiming at the engineering characteristics of roadway excavation under themining condition of adjacent working faces,the reasonable support of roadway and application effect are researched,thebolt-net-cable-grout combined support program of roadway is designed,the width of the protection coal pillars betweenthe roadways is reduced from50m to25m.In the course of roadway service,the maximum value of the two sides movecloser is805mm,the maximum value of the top and bottom floor move closer is880mm,the maximum value of the roofsinking is150mm,which can meet the mining demand of the follow-up face,and provide a theoretical basis forimproving the mining rate of resources and other issues.
