Full Title: Reproduction of a Complex Tracer Test through Explicit Simulation of a Heterogeneous Aquifer using Bayesian Markov Chain Monte Carlo

Simulation of tracer response curves in waste rock systems can be difficult using conventional numerical techniques, due to the Read more... about Reproduction of a Complex Tracer Test

With the increased drive towards deeper and more complex mine designs, geotechnical engineers are often forced to reconsider traditional deterministic design techniques in favour of probabilistic methods. These alternative techniques allow for the direct quantification of uncertainties within a Read more... about A Comparison of Traditional, Step-Path, and Geostatistical Techniques in the Stability Analysis of a Large Open Pit

Various Australian and international regulatory bodies (Environmental Protection Authority, 2015) require an early assessment of the geochemistry of waste rock. This usually includes estimates of the locations and volumes of potentially acid-forming (PAF) materials and requires sampling of the Read more... about Geostatistics and Sample Numbers from an Acid and Metalliferous Drainage Perspective

To assess the risk of acid and metalliferous mine drainage (AMD), most new mining projects require an initial assessment of the locations and volumes of potentially acid forming (PAF) waste that is likely to be moved and dumped in waste stockpiles. This requires sampling of

Resource estimation could be considered equal parts Art/Science/Math, due to its foundations in statistics and calculus, its incorporation of physical, chemical, and geological principles, and its requirement for subjectivity.
