为消除井巷涌水给生产和安全带来的危害,一些冶金矿山应用了注浆堵水技术。在水泥单液注浆、水泥水玻璃双液注浆等方面做了不少工作,积累和总结了很多经验。近几年来,广大科学工作者研制出多种新的化学注浆材料,能够解决水泥类注浆材料不能解决的堵水问题。(一)氰凝注浆材料及其堵水机理氰凝其主体成分是由过量的多异氰酸脂与端羟基聚醚树脂进行反应而得的低聚的聚氨基甲 In order to eliminate the hazard brought by the gushing water of the mine to the production and safety, some metallurgical mines use grouting and water blocking technology. In the cement single grouting, cement water glass double grouting, etc. done a lot of work, accumulated and summed up a lot of experience. In recent years, the majority of scientists have developed a variety of new chemical grouting material, can solve the cement grouting material can not solve the water blocking problem. (A) cyanide grouting material and its water shut-off mechanism The main component of cyanidation is excess polyisocyanates and hydroxyl-terminated polyether resin reaction oligomeric polyurethane
