- Abstract
The penetration of the tail slurry suspended particles leads to the phenomenon of clogging, a higher seepage line and impact on stability of tailings dam. First of all, study influencing factors of muddy water infiltrationan,then an indoor simulation experiment is conductedaccording to the former study, using a self-made muddy water seepage test instrument, and the evolution lawsof the coefficient of permeability of muddy water infiltration is analyzed, utilize it to correct related design parameters of a tailings dam, estimate the permeability function through particle size distribution curve which is obtained by laser particle size analyzer.By using the original and the adjusted parameter for simulation of the seepage field,the position and form of saturation line under two kinds of situations are obtained,and by using strength reduction finite element method ,dam body stability is simulated under three kinds of working conditions at the time of the high end,the result is that the stability safety coefficients all decreased obviously when considering the muddy water seepage law.Thus, the stability of tailings dam can be reduced by the deposition of silt.
