摘要
针对胜利煤矿永冻层下浅埋14#煤层的赋存特殊性,在14101工作面运输顺槽开展锚网支护试验及现场测试工作,分析冻土矿区浅埋煤层巷道掘进过程中巷道围岩变形规律和锚网支护的实际承载变化规律,为评价这种条件下锚网支护的合理性、制定冻土矿区浅埋煤层巷道锚网支护技术标准及规范提供了理论依据。
Aiming at the special occurrence condition of shallow 14# coal seam under permafrost in Shengli mine,have conducted bolting support experiments and on-site tests in 14101 working face roadway. Analyze the roadway deformation and actual bearing load of the bolting system during the shallow coal seam roadway excavation under the permafrost. These study lay the groundwork for evaluating the rationality of the bolting support system,and provide technical standard for roadway support theoretically for roadway excavation under permafrost.
