区域治理是防治煤矿底板水害的有效手段。本文针对云驾岭矿19101工作面治理过程中大注浆量问题，以不同注浆材料配比制浆、取样、化验，通过浆液结石体与泥岩抗压强度值比对、隔水层阻水系数2个方法确定，水泥与粉煤灰3∶7的配比是可以满足底板水防治要求的。同时，将试验结果推广应用，并跟踪、监测井下钻探、物探以及回采涌水结果均表明治理效果显著。注浆材料优选技术可以为注浆量大的工程项目提供有益借鉴，助力煤矿企业降本增效，提升发展质量。

Regional governance is an effective means to prevent and control water disaster in coal mine floor. In this paper, aiming at the problem of large grouting volume in the treatment process of 19101 working face in Yunjialing Mine, different grouting material ratios are used for pulping, sampling and testing. The ratio of cement to fly ash 3:7 can meet the requirements of floor water prevention and control by comparing the compressive strength value of slurry stone body and mudstone and the water resistance coefficient of aquifuge. At the same time, the test results are popularized and applied, and the results of tracking and monitoring underground drilling, geophysical prospecting and mining water inrush show that the treatment effect is remarkable. The optimization technology of grouting material can provide useful reference for engineering projects with large grouting volume, help coal mining enterprises to reduce costs and increase efficiency, and improve the quality of development.
