The Analysis of Stability of Mine's Tailing Dam Based on the FLAC3D

Abstract

Tailings dam is an important part of engineering construction of tailings pond. Stability analysis of tailing dam is of great significance, because it is the significant security risk of the project of tailings. FLAC3D program which based on Lagrange algorithm is especially suitable for solving the nonlinear large deformation problems in rock and soil mechanics engineering. After the adequate mastery of the soil layer structure, the physical and mechanical properties and the determination of the calculation parameters, the engineering software of FLAC3D and the numerical analysis method are utilized to analyze the integral stability of the tailing dam of Guangxi Xinfa Aluminum Company in Jingxi county. It can provide a scientific basis for the stability analysis of engineering construction of another tailing pond.
