强岩溶地区主过水通道注浆封堵技术探讨

Discussion of Grouting Plugging Technology for Main Water Channel in Strong Karst Area

摘要:

矿山帷幕注浆技术由于其具有安全、环保、经济、高效等特性，已在国内多个矿山堵水中成功采用，取得了很好的堵水效果。而在强岩溶地区，动水注浆技术，尤其是矿区主过水通道封堵质量将直接影响帷幕的堵水效果，甚至决定着工程的成败。以广东凡口铅锌矿帷幕注浆工程为背景，探讨强岩溶地区主过水通道封堵技术。

Abstract:

Because of the characteristics of safety, environmental protection, economy and high efficiency, the mine curtain grouting has been successfully implemented in mines with good effects of water plugging. While in strong karst area, the water plugging effect will be directly influenced by the dynamic water grouting technique, especially by the plugging quality of main water channel, which is the key factor affecting the success of the project. With the background of a curtain grouting engineering in Fankou lead-zinc mine of Guangzhou, the paper discusses the grouting plugging technology for main water channel in strong karst area.
