... tailings shows a baseline geostatic stress ratio K₀ = 0.6 for those tailings that are truly normally consolidated. Other geological history factors, including compaction by tracking and wetting–drying cycles, adds about a Δσ_h ≈ 60 kPa ‘locked-in’ stress...

...Changkun Ma, MSc; Chao Zhang, PhD; Xiaogang Guo, PhD; Hanmin Zhou, PhD; Shucheng Gan, BSc Fine-grained tailings have poor permeability and a long consolidation time, but treatment with flocculants can improve their mechanical properties. Changes in the physical and engineering properties of fine...

...Michael Jefferies, PEng The last two decades have seen five large tailings dam failures, which developed suddenly and statically with damages of US$ billions and many deaths. These are company-threatening events, far outside societal tolerance, with investors questioning the situation. While media...
