Causes of Tailings Storage Facility Failures

Meeting information:

The meeting was held on Monday 10 February 2020 from 5.30pm – 7.00pm at the Celtic Club, Ord Street, West Perth

Presentation information:

There have been a number of Tailings Storage Facility (TSF) failures in the mining industry over recent years. In particular, the most recent failure at Brumadinho led to a significant number of fatalities. This TSF had been inactive for a number of years at the time of failure. A failure under such circumstances differs in some ways from common wisdom in the mining industry, which suggests a TSF generally becomes “safer” after deposition has ceased. This presentation will discuss various failure mechanisms for TSFs that are potentially applicable to inactive TSFs, and how the management of these should be considered following operations, in particular during closure design and construction works.

Speaker information:

David Reid, Research Fellow, UWA
David is a Research Fellow at UWA, working on an industry-supported ARC research project on the static liquefaction of tailings. He has 15 years’ experience in the tailings industry focussed on TSF failure mechanisms, stability analyses, numerical modelling, laboratory testing, and in situ characterisation.
