How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Soil water characteristic curves (SWCCs) used for the design of covers over mine wastes, are typically determined in the laboratory by performing drying tests on samples in a Tempe cell. In some cases, re-wetting is also carried out. The advantage of using drying tests is that they are carried out from the saturated state at a given sample test den...
Article
The conventional deposition of mine tailings as a slurry in seepage, with the potential to contaminate surface and ground waters, particularly during deposition, and possibly post-closure. In a dry climate, tailings deposition can be cycled to largely evaporate excess water, and on closure the tailings may remain desiccated to the extent that incid...
Article
Mine rock typically emerges from an open pit relatively dry, and is conventionally stored in surface dumps where it progressively becomes wet-up by rainfall infiltration over time, accompanied by some base seepage. Rainfall infiltration into a bare, loosely-dumped rock dump is commonly assumed to be 30 to 60% of average annual rainfall, depending o...
Article
Between 2004 and early 2006 a large-scale, instrumented, potentially contaminating trial waste rock dump was constructed and monitored at Cadia Hill Mine, in NSW, Australia. The trial waste rock dump was instrumented with lysimeters to measure rainfall infiltration and seepage through its base, and temperature sensors and gas sampling tubes to eval...
Article
Understanding how rainfall infiltrates, is stored within and is transported through surface waste rock dumps is essential to predicting the release rates of mineral weathering products to the environment. Infiltration is commonly assumed to be 50% of annual rainfall. There are however a lack of field data to confirm this. Further, there is poor und...
