摘要
在对2103运输顺槽掘进工作面基本情况和注浆加固机理研究的基础上,根据实际情况确定了注浆材料及其配比、注浆方案和相关参数、注浆工艺。经实践表明,采用注浆方式对顶板进行加固后顶板整体性和稳定性得到明显提升。
Based on the research on the basic situation and grouting reinforcement mechanism of 2103 transportation trench heading face,the grouting material and its ratio,grouting scheme,relevant parameters and grouting technology are determined according to the actual situation.The practice shows that the integrity and stability of the roof are significantly improved after the roof is reinforced by grouting.
