对于破坏严重的巷道,传统的方法只能是架设U型钢支护,这样做不但消耗大量的人力、物力,而且效果也不佳。经过分析论证,并结合已有的巷道支护技术成果,认为通过向支护体后注入具有固化作用的浆液提高围岩的整体性,进而提高围岩自身的承载能力,可达到减轻巷道破坏程度的目的。
For the serious destruction of the roadway, the traditional method can only be set up U-shaped steel support, this will not only consume a lot of manpower, material resources, but the effect is not good. After analysis and demonstration, combined with the existing roadway support technology results, that through the support body after the injection of a solidification of the slurry to improve the integrity of the surrounding rock, thereby increasing the carrying capacity of surrounding rock itself can be achieved to reduce the degree of roadway damage the goal of.
