露井联采耦合作用下输煤巷道稳定性评价及控制技术

    Evaluation of Coal Handling Roadway Stability Under the Coupling Action of Open-underground Combined Mining and Controlling Technology

    • 摘要: 由于露天开采与井工开采相互作用,相互影响,形成1个复杂的动态耦合场,为解决露井联采耦合作用下输煤巷道稳定性问题,以安太堡露天矿为工程背景,以FLAC3D 软件为平台,对典型剖面进行稳定性分析与评价,得出在巷道设计时,应对左侧巷道采用锚喷支护的结论。

       

      Abstract: Due to the Interaction and mutual influence of open-pit mining and underground mining, there is a complex dynamic coupling field. In order to solve the stability problem of coal handling roadway under the coupling action of open-underground combined mining, taking Antaibao Open-pit Mine as engineering background and FLAC3D software as plat gram, through the stability analysis and evaluation of typical profile, the study obtained the conclusion that the left side of the roadway should be supported with shotcrete in roadway design.
