摘要
通过注浆方式对断层进行治理,并以31105采煤工作面过断层为例,对超前注浆加固材料选择、注浆方案以及现场应用效果等进行分析。在回采巷道内对断层影响范围进行超前注浆,提高破碎煤岩体稳定性、承载能力,确保采面过断层效率以及安全保障能力。
It is proposed to treat the fault by grouting. Taking the fault crossing of 31105 coal face as an example, the selection of advanced grouting reinforcement materials, grouting scheme and field application effect are analyzed. Advance grouting shall be carried out in the affected area of the fault in the mining roadway to improve the stability and bearing capacity of broken coal and rock mass, and ensure the fault crossing efficiency and safety guarantee ability of the mining face.
