摘要
针对煤巷锚网索支护围岩变形的问题,在不同采深的条件下,通过相似模拟试验,得出了工字钢支护、锚梁网支护以及锚网索支护的巷道围岩变形破坏规律,对不同支护方式的适应范围作了详细的分析。
Aiming at the problem of surrounding rock＇s deformation of coal roadway supported by cable anchor, get the deformation destroy rule of laneway surrounding rock supported by joist steel support, anchor beam support and cable anchor support at the condition of different mining depth, through similar simulation test, also detailed analysis is made on adaptation range of different support pattern.
