摘　　要：以郁山煤矿-220 m水平北翼运输大巷为研究对象,借助于D/Max-3B型X射线衍射仪对围岩的物理成分进行检测。通过分析巷道工程地质条件,阐述了巷道围岩变形破坏的机理,提出了混凝土反拱+锚索锚注+马蹄形全封闭金属支架联合支护的施工方案,并进行了工业性试验。井下试验表明,该联合支护形式有效地控制了北翼运输大巷的整体变形和破坏,使其能够满足正常生产需要,并获得了较好的技术经济效益。Takes -220 m level, north wing transport roadway in Yushan coal mine as the research object, de- tects the physical components of the surrounding rock by means of D/Max -3B type X -ray diffraction. Through ana- lyzing the geological conditions of roadway engineering, expounds surrounding rock deformation and failure mecha- nism, puts forward the combined support construction program of concrete inverted arch ＋ anchor cable and bolt - grouting ＋ horseshoe full enclosed metal support, and carries out industrial trials. Underground test showed that the form of joint support effectively control the overall deformation and destruction of the north wing transport roadway, en- able it to meet the production needs, and get a better technical and economic benefits
