我国矿区注浆帷幕截流技术的研究与应用

RESEARCH AND APPLICATION OF CURTAIN GROUT TECHNOLOGY FOR FLOW CUT-OFF IN CHINA'S MINES

针对我国大水矿床开采中因地下水所造成的危害及环境破坏问题,产生了注浆帷幕截流技术,它已成为我国大水矿山地下水防治的一项主要技术。本文在总结我国大水矿山使用注浆帷幕截流技术的基础上,对帷幕防渗标准、帷幕结构、注浆孔施工、造浆及注浆系统、注浆参数等提出了建设性意见;同时也指出了矿区帷幕注浆技术的选用条件。

The curtain grout technology for flow cut-off, evolved in the process of eliminating danger and its environmental damage caused by ground water, has become an important option for prevention and control of ground water hazards in the exploitation of large water flow deposits in China. On the basis of a review of this aspect in China, a standard for permeation prevention, curtain structure, injection hole drilling, preparation of grout, grout injection system and grout parameters were discussed and constructive suggestions were made. The application conditions of this technology in mine fields were described also in this paper.
