摘　　要：大倾角大断面交岔点施工应既能适应当前煤矿巷道掘进支护技术发展的趋势,也能满足实际地质状况和巷道本身服务性质的要求。巷道采用导硐分层施工法,采用综合机械化方式施工,支护采用锚网索喷+U29型钢架联合支护方式,既加快了施工速度,又满足了大断面巷道的支护强度,同时创新了施工工艺。The construction of large span intersection at large inclined angle should not only adapt to current trends of roadway tunneling support technology development in the coal mine, but also to meet the requirements of the actual geological conditions and the nature of itself. The pilot tunnel method was taken in roadway, mechanized construction was used, and bolt-mesh- shotcreting ＋ U29-type steel support were used, which not only speed up the construction speed, and meet the support strength in large span section of roadway, while innovated construction technology.
