Importance of the simple shear loading direction to the stability of tailings
The engineering properties of soils and tailings often exhibit significant anisotropy. One area where this has been well documents is undrained shear strength. Materials sheared in directions close to the…
Predicting changes in static liquefaction susceptibility using cone penetrati...
Flow liquefaction is a geotechnical hazard in mine tailings facilities. Soil states that are contractive, or loose of the critical state line, are susceptible to flow liquefaction. Tailings facilities are…
Instrumented column testing of salt uptake from compacted red mud into a cover
A cover of inert material overlain by topsoil is proposed over compacted, seawaterneutralised red mud, a waste product from the refining of bauxite to produce alumina, at Queensland Alumina Limited…
Material handling testing and control system requirements for dry stack tailings
The challenges of increasingly scarce water resources and the risk of dam failures has seen the mining industry turn to sustainable tailings management solutions such as dewatering and dry stacking….
The development of soil water characteristic curves for soils types classifie...
The soil-water characteristic curve (SWCC) is one of the most essential soil properties in unsaturated soil mechanics. The water flow and storage characteristics of an unsaturated soil are closely related…
Characterisation of pore pressure in a tailings dam and the implications for ...
Klohn Crippen Berger (KCB) was appointed as the external review consultant for the design of upstream embankment raises for two bauxite “red mud” tailings storage facilities (TSFs) in Queensland. A…
Potential improvement of tailings geotechnical behaviour using bacteria
Despite the recognised importance of tailings management, there remain little data on the potential benefits of biological treatments compared with physical and chemical treatments. The operation of the majority of…
Decommissioning of a 100 hectare Tailings Storage Facility containing contami...
A 100 hectare Tailings Storage Facility in the Northern Territory recently reached full capacity and was scheduled for decommissioning. This paper presents an overview of the design and construction challenges…
Optimisation of constant rate of loading slurry consolidometer testing of fin...
Fine-grained coal tailings slurry undergo only limited settling and self-weight consolidation, and tend to remain slurry-like and unsuitable for conventional laboratory consolidation testing. In addition, constant rate of loading consolidation…
Lessons learnt in geotechnical investigation and stability analysis for upstr...
Upstream embankment raises often represent the lowest cost option for increasing the capacity of tailings storage facilities (TSF), but also pose the highest stability risk due to constructing on top…
