Abstract

For the production safety of the tailings dam, a midterm tailings dam system stability assessment is needed. With numerical methods, aiming at the specific examples of projects the seepage stability, the statics stability and the dynamics stability are calculated, Results show there is no infiltration of the overflow from the slope, little hydraulic gradient and seepage stability. Safety factors meet regulatory requirements and the dam is in static stability. Dynamic responses from the dam and liquefaction results of the dam show that the dam is stable. The study provides a comprehensive assessment of the stability line. The calculation with the numerical simulation of the tailings has a certain reference value and significance.
