摘要: 槽孔管排渗是一种新兴的尾矿坝排渗技术。基于达西渗流定律、质量守恒定律和反滤层排水降压原理,通过理论分析和总结前人的研究成果,研究槽孔管排渗机理及其计算方法。通过建立槽孔管排渗系统理论计算模型,推导出等效反滤层半径、系统总渗流量计算公式。通过工程实例验证了理论研究成果的合理性。

Abstract: Slotted pipe drainage is a new drainage technology of tailings dam. Based on Darcy′s seepage law,mass conservation law,drainage and depressurization principle of filter layer,the calculation method and drainage mechanism of slotted pipe are explored by theoretical analysis and summarizing the previous studies. The system′s equivalent radius of the filter layer and the general seepage draining equation are deduced by establishing the theoretical calculation model. Then,the rationality of the theoretical research is verified through engineering examples.
