摘　　要：为了解决破碎软岩巷道支护难题,以辛置煤矿布置在泥岩中的310轨道巷为工程背景,综合采用现场调研、围岩松动圈探测以及围岩力学参数测试等方法,揭示了围岩变形破坏机理,提出了"锚网索喷注"联合支护方案。数值模拟和现场监测表明,新支护方案实现了对破碎软岩巷道变形的有效控制。In order to solve the problem of supporting the broken soft rock roadway, the 310-track lanearranged in the mudstone is used as the engineering background. The method of field investigation, thedetection of the surrounding rock and the test of the mechanical parameters of tbe surrounding rock arecarried out to reveal damage mechanism of surrounding rock, put firward the ＂anchor net cableinjection＂ joint supporting program. The numerical simulation and field monitoring show that the newsupporting scheme realizes the effective control of the deformation of broken soft rock roadway.
