摘　　要：对地面难以封堵的高水位封闭不良水文长观孔采取在井下封堵的方案,通过物探与钻探相结合、封孔与堵源相结合,地面与井下注浆系统相结合的办法,对水文孔上下的含水层注浆封堵,从而切断水文孔周围含水层之间的水力联系,再进行效果分析、验证、评价,达到治理钻孔水害的目的。The high - water poor sealing hydrology long - term observation hole which is hard to seal on the ground uses underground sealing scheme. Through the methods of geophysical prospecting combined with drilling, hole - sealing combined with plugging, ground combined with underground grouting, the aquifers up and down the hydrological holes are carried out sealing grouting to cut down the hydraulic connection of aquifers around the hydrological holes, and then effect analysis, verification and evaluation are carried out to get the goal of controlling drilling water diaster.
