    Numerical Simulation of Rock Control Technology for One Thousand Meters Depth Roadway

    • 摘要: 华丰煤矿属于典型的千米深井巷道,采用FLAC3D软件建立了三维数值计算模型,设计了6种典型的巷道支护方案,结合巷道围岩破坏特征分析了千米埋深巷道围岩支护方案及支护参数,结果显示全断面锚注支护具有全断面支护、变形小等优点,是一种非常合理的支护方案。

       

      Abstract: Huafeng Coal Mine belongs to the typical km deep well roadway. In this paper, a three-dimensional numerical caculation model was established by FLAC3D,6 typical support schmes were designed, the support schme and parameters of km deep well roadway were optimized by analyzing the failure teatures of surrounding rock, the results showed that the full section bolt-grouting support had the advantages of full section support and small deformation, so it was a extremely reasonable support scheme.
