“氰凝”堵漏是近期内发展起来的新技术，对钻孔中的裂隙漏水和小溶洞漏水进行堵漏有其特殊的效果。我队在党委的领导下，从1975年第二季度以来开展了向复杂地层进军的群众运动，开始了“氰凝”堵漏的试验研究工作。在北京市101地质队、天津大学、311地质队等兄弟单位的大力支持和协助下，我们进行了六十多次的室内试验研究和十次孔内堵漏试验工作，均取得了一定的成果。
“Cyanidation” plugging is a new technology that has been developed in the near future. It has special effects on the leakage of crevice leaks and leakage of small caverns in boreholes. Under the leadership of the Party Committee, our team has launched a mass movement that has entered the complex stratum since the second quarter of 1975, and has started the experimental research on the “cyanide condensation” plugging. With the support and assistance of Beijing 101 Geological Team, Tianjin University, 311 Geological Team and other fraternal units, we conducted more than 60 indoor laboratory studies and 10 hole plugging tests, all of which achieved certain results. .
