引流注浆封堵深基岩冻结井筒冻结孔涌水技术

Sealing Deep Freezing Bedrock Shaft Frozen Hole Bursting Water Technology with Water Diversion Grouting

针对我国西部地区深基岩冻结井筒冻结孔涌水水害技术难题,以胡家河矿主立井冻结孔水害治理项目为工程背景,在分析封闭不良冻结孔环状导水通道生成及涌水机理基础上,创新性提出一种引流注浆封堵深基岩冻结井筒冻结孔涌水技术。工程实践验证分析研究结果正确,该技术能高效快速治理冻结孔涌水水害。

For the frozen hole bursting water technical problems of deep freezing bedrock shaft in West area of China, taking water dis- asters control project in Hujiahe main shaft freezing hole as engineering background, on the basis of analyzing annular conduit water channels formation and bursting water mechanism of the frozen hole, the paper innovatively presents the water diversion grouting sealing technology. Through engineering practice verification, the analysis conclusion is valid. The technology could control the frozen hole bursting water disaster effectively and quickly.
