深部巷道支护材料的选型研究

Study of Deep Roadway Material Selection Study

通过对深部巷道支护材料及支护施工机具的选型进行研究,深入分析支护部件的力学性能和几何参数。介绍了常村煤矿在破碎围岩强力锚杆锚索支护井下试验中采用的各种机具,分析它们的技术特性和使用条件,合理选型并应用于工程实践,技术经济效果显著。

Through deep roadway construction materials and supporting equipment selection studies,in depth analysis of the mechanical properties of supporting components and geometry.Describes the often strong village coal mines in the broken rock bolt anchor supporting a variety of downhole test equipment used to analyze their technical characteristics and conditions of use,a reasonable selection and applied to engineering practice,technical and economic results are obvious.
