摘要
运河煤矿-725m东翼轨道大巷,底板松软、围岩破碎,抗压强度较低。通过合理的注浆工艺和注浆参数,破碎围岩的完整性明显提高,在外载作用下具有较强的整体抗变形能力。
Yunhe coal mine -72.5 East track roadway, soft bottom, rock crusher, a lower compressive strength. Through the rational process of grouting and grouting parameters, broken markedly improved the integrity of rock, set out under the overall has a strong anti - deformation capacity.
