Tailings and Mine Waste Conference

If it creeps, does it matter? Znidarčić, Dobroslav

Abstract

Creep effects are among the last phenomena in soft tailings behavior still needing comprehensive study. Evidence of creep effects have been reported, but rational evaluation of its significance on tailings disposal facility design is still lacking. The paper presents a parametric study in which the nonlinear finite strain consolidation theory is applied to evaluate potential creep effects on the storage capacity and settlement rates of a hypothetical tailings disposal facility. The analyses compare consolidation results for highly compressible tailings having low hydraulic conductivity with and without creep effects. The increase in storage capacity and reduction in settlement rates are quantified in the paper.
