Abstract: The deposition law of tailings in tailings pond is complex and ever-changing, which makes tailing seepage field more complicated.The method of three dimensional flow field is more applicable on seepage flow characteristic simulation of the tailings.The three dimensional seepage finite element method is used to simulate the seepage field high status and the final level of tailings pond, which has a significant guidance for tailing pond's later security management.

Key words: Tailings pond, 3D seepage flow field, Finite element analysis
