    摘要:

    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,以胡家河矿主立井井筒冻结孔水害治理工程为实例,分析了冻结孔环状导水通道生成及涌水机理,进而提出一种创新性的逆流引流注浆封堵技术,并介绍了该技术的原理及施工工艺。工程实践证明,该技术能高效快速治理冻结孔涌水水害。

    Abstract:

    In order to solve the water disasters caused by freezing holes of full-depth bedrock frozen shaft in western China, analysis was made on the form of annular water-transmitting channels in freezing holes and the in-rushing water mechanism with the case of water disasters control project of Hujiahe coal mine. The paper presents an innovating counter-flow water diversion grouting sealing technology and introduced its principle and construction process. The project practice proved that this technology can effectively and quickly control the in-rushing water disaster of freezing hole.
