摘 要:针对赵庄煤业复用巷道变形剧烈的问题,实测了巷道变形规律,分析二次锚注加固机理,制定一次超前锚注加固、稳定区二次注浆加固方案。采用二次锚注加固方案后,两帮变形量与未锚注区域相比减小50%,其中剧烈变形区和稳定区减小48%。In view of the severe deformation of the reused roadway in Zhaozhuang Coal Industry,the deformation law of the roadway is measured,the mechanism of the secondary anchoring and grouting is analyzed,and the scheme of the primary leading anchoring and grouting and the secondary grouting in the stable area is formulated.The deformation of the two sides is reduced by 50% compared with that of the non anchored area,and the severe deformation area and the stable area are reduced by 48%.
