摘要 针对深部近距离煤层跨采巷道受多次采动影响巷道围岩变形严重等问题,采用理论分析、数值模拟及现场观测的方法,研究了巷道合理的位置及支护参数。确定113_下08运输顺槽布置位置与113_上01工作面运输顺槽水平距离为27 m,提出了锚网和锚索耦合支护的分段动态支护手段。 Aiming at the problem of roadway surrounding rock serious deformation of the deep short distance change spacing roadway under overhead mining influenced by multiple mining, using the methods of theoretical analysis, numerical simulation and field measurement, the reasonable position and supporting parameters of the roadway under overhead mining were studied. The layout location of the No.113down08 transport crossheading was 27 m horizontal distance from the No. 113upO1 working face transport crossheading. The pieeewise dynamic support means based on the bolt-net-anchor coupling support was determined.
