摘要
以复合顶板深孔预注浆加固为对象开展研究,结合具体工程实际,在分析合理加固层位和钻孔布设等的基础上,对合理确定注浆加固时机、注浆量及注浆效果逐一做了分析和总结,希望能够为其他矿井相似工程的开展提供借鉴与参考。
Taking deep hole pre-grouting reinforcement of composite roof as an object of study, combined with the actual engineering, based on the analysis of reasonable reinforcement horizons and borehole layout, this paper made analysis and summary of reasonably determing grouting reinforcement timing, grouting volume and grouting effect one by one, hoping to provide reference for similar projects in other mines.
