以晋煤集团成庄矿大采高复用巷道注浆加固为工程背景,分析了复用巷道在一次采动及二次采动影响条件下的巷道变形分区特征,结合浆液渗透特性,确定了合理的巷道一次注浆及二次注浆时机,并进行了注浆加固工业性试验。结果表明,注浆加固效果显著。
Based on the engineering background of Grouting Reinforcement of Large Mining and High Complex Roadway in Chengzhuang Coal Mine of Jincheng Coal Mine, the characteristics of roadway deformation zone under the condition of primary mining and secondary mining were analyzed. Combined with the seepage characteristics of slurry, Reasonable roadway once grouting and secondary grouting timing, and carried out the grouting reinforcement industrial test. The results show that grouting reinforcement effect is significant.
