摘　　要：为了解决矿井井筒在富水地层中的渗水问题,采用无毒无害且胶凝时间可控的水泥-水玻璃浆液治理矿井井筒的渗水漏水问题。通过室内实验确定酸性条件下水泥水玻璃浆液的胶凝时间和结石体强度。根据井筒渗水地层的地质条件提出井筒壁后注浆的注浆方法以及最佳的浆液配比。研究表明水泥水玻璃可以很好地封堵岩土体的裂隙,阻断地下水的渗流路径,水泥水玻璃浆液可以作为封堵材料用于治理矿井井筒渗水漏水。In order to solve the problem of water seepage in mine shaft in water-rich strata,the author introduces the application of a non-toxic and non-hazardous cement-water-glass slurry with a controlled cementing time,including the cement-water-glass slurry's cementing time and crystalline body strength under acidic conditions determined through indoor experiments and the grouting method for post-wall grouting and the optimum slurry ratio proposed based on the geological conditions of the seepage stratum in the shaft,which can seal the fissures in the geotechnical body and block the seepage path of groundwater,controlling water seepage and leakage in mine shaft.
