近年来,我国在很多资源丰富的矿区进行新矿井建设,不得不采用“特殊凿井”方法来通过工程地质及水文地质条件复杂的松软含水不稳定地层.而科学研究成果应用于矿井建设,大大地促进了特殊凿井技术的发展.高分子化学工业的发展,使注浆法取得了突破性的进展.五十年代以来,先后在美国、日本等国家发明了可控制凝胶时间、可注入粉细砂层的有机化学浆液.我国研制的丙凝、氰凝等有机化学浆材,成功地解决了矿井、水坝等各类工程的防渗、加固与堵漏,而相邻学科和技术的发展也促进了特殊
In recent years, China has constructed new mines in many resource-rich mines and has to adopt “special sinking” methods to pass the complicated soft and water-bearing instable formations where the engineering geological and hydrogeological conditions are complex. The scientific research results are applied to mine construction, To promote the development of special shaft sinking technology.The development of macromolecule chemical industry has made a breakthrough in grouting method.From the 1950s, it has been invented in the United States, Japan and other countries can control the gel time can be injected Fine sand layer of organic chemical slurry developed in China Propane condensate, cyanide condensate and other organic chemical pulp, successfully solved the mine, dam and other projects seepage, reinforcement and plugging, and adjacent disciplines and technologies Development has also promoted special
