摘　　要：针对嵩山煤矿二;煤层高应力三软煤巷支护困难,分析现有三软煤巷断面形状和支护方案存在的问题,确定了煤巷采用斜墙圆弧拱断面,提出了“钢棚+全锚索”复合支护技术,并在2112工作面上顺槽成功实施,巷道围岩控制效果良好。In view of the difficulties in supporting the high stress three soft coal roadway in the Two-one coal seam of Songshan Coal Mine,the problems existing in the cross section shape and support scheme of the existing three soft coal roadway are analyzed,the inclined wall circular arch section is determined,the compound support technology of "steel shed + full anchor cable" is put forward,and it has been successfully implemented in the 2112 working face,the surrounding rock control effect of the roadway is good.
