| 摘 要： | 通过分析高应力状况下的巷道破坏机理,比较不同的巷道支护形式,指出锚注支护是一种适用于高应力破碎巷道的比较合理的支护方法。注浆加固实验表明,注浆岩体强度比未注浆有了很大程度的提高。锚注支护通过改善围岩内部结构,发挥其自身承载能力,提高了巷道的稳定性。

| Abstract: | According to the analysis of failure mechanism in high stress roadway and comparison of different roadway supports,the authors have pointed out bolt-grouting support is a reasonable support which suits for high stress breaking roadway.Experiments of grouting reinforcement indicate that the intensity of grouted rock mass is higher than that of non-grouted.Bolt-grouting improves roadway stability by improving the inner structure of wall rock and playing its loading ability role. |
