Abstract

With the high development of the mine enterprise in China, the scale of the tailings' design is becoming bigger and bigger, the safety of the tailings becomes more and more important. As one of the most important parts, the tailings dams turn to be 'disaster zone' with frequent accidents. Therefore, Tailing Dam's stabilities is particularly important. This paper based on the theory of Seepage coupling and Stability analysis, taking the powerful non-linearly finite element software ABAQUS to make simulation analysis of tailing dam, and comparative analysis with the results of classical ultimate balance method, the concluding part raises the prospect of methods for stability analysis of tailing dam. Considering un-saturation coupling between seepage and stress, the article builds two-dimensional tailings dam model, then simulates or computes it applying ABAQUS. Strain-stress, displacement, plasticity and saturation line nephogram could be acquired by powerful graphical post-processing module. The safety factor of the dam could be obtained by strength reduction method.
