摘要
为解决深井高应力巷道围岩变形严重、支护困难的技术难题,本文采用数值模拟、工业性试验等方法对五阳煤矿7608工作面运输巷围岩变形规律以及支护参数进行了分析与研究。结果表明,随着采动影响的加剧,巷道围岩非连续变形及非对称变形均也逐步加剧,在采用新支护方案后,巷道顶底板及两帮变形量最终稳定在240 mm、320 mm,说明采用锚网索联合支护方案能够有效控制巷道围岩变形破坏。
In order to solve the technical problems of deep shaft high-stress roadway deformation and serious support difficulties, the numerical simulation and industrial tests were used to analyze the deformation law and support parameters of the surrounding roadway in 7608 working face of Wuyang Mine. The results showed that with the intensification of mining, the discontinuous deformation and asymmetric deformation of the surrounding rock of the roadway were also gradually intensified. After adopting the new support scheme, the deformation of roadway roof, floor and two sides finally stabilized at 240 mm and 320 mm, it showed that the combined support scheme of anchor, net and cable can effectively control the deformation and failure of roadway surrounding rock.
