摘要
根据车集煤矿深部28轨道下山的地质状况,运用有限元数值模拟软件FLAC5.0研究巷道软岩大变形机理,通过现场工业性试验及二次支护,巷道变形得到有效控制,从而找出了解决深井软岩巷道的支护的一般规律。
According to geological condition of 28 track down at Cheji Coal Mine, the finite element numerical simulation software FLAC5.0 was used to study the large deformation mechanism of soft strata roadway. According to the industrial tests and the twice supporting, the deformation of roadway gets effectively control, the effect of surrounding rock control is good.
