尾矿库排渗工程技术方法

Technological Method of Seepage Drainage of Tailing Pond

摘要:

为消除或减少尾矿库的安全风险，重要措施就是降低尾矿库坝体内的浸润线，而排渗工程技术方法是其主要手段。本文结合部分岩土工程技术在尾矿库排渗工程中的运用，并通过多项工程实践，系统讨论与总结尾矿库排渗工程技术方法中的盲沟排渗法、水平孔排渗法、辐射井排渗法、井点管抽水法、其它联合排渗措施的原理特点、施工方法与质量控制要点。

Abstract:

The important measure to eliminate or reduce the safety risk of tailing pond is to reduce the saturation line in the dam body, and the seepage drainage technology is the main means. Based on the application of some geotechnical engineering technology in the seepage drainage project of tailing pond and with a number of engineering practice, this paper discusses and summarizes the blind ditch drainage, horizontal hole drainage, radiation well drainage, well point pipe drainage and some other combined drainage measures about their principles, characteristics, construction methods and quality control points in tailing pond seepage drainage engineering technology.
