Static Liquefaction and Strength Loss in Tailings Dams

Apr 11, 2018 · Static liquefaction and strength loss of tailings dams due to undrained failure has become a topic of interest in tailings management following the Fundão and Mount Polley tailings dam failures. Static liquefaction is the sudden loss of strength when loose soil, typically granular material such as sand or silty sand, is loaded and cannot drain.

Tailings Dam Failures: A Review of the Last One Hundred Years

tailings dam failures by dam height. Failures are found to mainly occur in dams with heights of up to 30 m. A plausible reason may be that unconsol-idated materials with high pore water pressures in such relatively low dams (possibly in their early stages of devel-opment) are yet to develop adequate shear strength to counter the resisting forces.

Can machine learning predict tailings dam failure? | PETRA

Tailings dams can fail very suddenly, and with little warning, particularly if liquefaction of the tailings is triggered. "While drainage is designed to control the phreatic surface in the tailings dam to maintain stability, they can malfunction and fail, and piezometers may not be sufficient to detect this. Perhaps UAV geophysics has a role in enabling AI to detect anomalies in the ...

Best Practices for Tailings Dam Design - Klohn Crippen

While using tailings materials to build the dam reduces construction costs, upstream tailings dams may be less stable than other designs under static loading and in the event of an earthquake (i.e. under dynamic loading), because tailings materials may liquefy and lose their strength (McLeod and Bjelkevik 2017). In some seismically-active countries, such as Chile, upstream tailings dams are ...

Design a Dam for Mill Tailings

With any type of major dam construction a complete hydrology study, including a determination of the amounts of milling, domestic, and excess water, must be made for design purposes. Often this information is available at no cost from State and Federal water resource agencies. The design of the dam must allow for the total natural and artificial runoff, so that when the area is abandoned the water can pass through or around the dam without soil erosion or undesirable impoundment occurring.
