ABSTRACT: Filtered tailings are popular in the mining industry because they can reduce the risks associated with the physical stability of filtered tailings storage facilities (FTSFs), especially for mine sites located in remote and Arctic regions. Understanding the creep, long-term strength, and compressibility characteristics of frozen filtered tailings is essential in properly designing FTSFs and reclamation covers in continuous permafrost regions. This article first aims to present the experimental approach that was developed to assess the short-term creep properties of frozen filtered tailings using temperature-controlled uniaxial constant-load tests. Preliminary results indicated that unsaturated specimens experienced more significant displacement than saturated samples. The creep rate changed according to the stationary and non-stationary creeps. This study also provides insights on the ability of existing creep constitutive models to describe and predict the creep of frozen filtered tailings.
