An approach to evaluation of field CPTU dissipation data in overconsolidated fine-grained soils
Download1999
Campanella, R., Robertson, P. K., Woeller, D., Sully, J.
Abstract: Dissipation of excess pore pressures during piezocone testing in firm to stiff overconsolidated fine-grained soils provides data curves that cannot be interpreted using published theoretical solutions. Available solutions are based on either cavity-expansion or strain-path methods,...

Anaerobic biodegradation of hydrocarbons in different oil sands tailings ponds: key microbial players and main activation pathway of hydrocarbon biodegradation
DownloadFall 2016
Anaerobic biodegradation of hydrocarbons is an important process in oil sands tailings ponds, which directly affects consolidation of tailings and extent of greenhouse gas emissions from tailings ponds. Since tailings ponds from different operators differ due to extraction process, age of...

The objective of this study was to determine if there was any difference in the bioremediation of oil sands process-affected water (OSPW) and to quantify and identify bacteria present in different scenarios. Two reactors were compared in this study: an acetic acid amended OSPW bioreactor, (AAAO...

One of the current technologies used by the oil sands industry to reduce the volume of fluid fine tailings and create a dry landscape is production of CT (Composite Tailings) and NST (Non-Segregating Tailings). CT and NST are engineered tailings streams obtained by recombination of fines (MFT or...

A large amount of fluid fine tailings (FFT) is stored in tailings ponds and is continuously accumulating from the extraction of bitumen from oil sands ore in northern Alberta. The FFT are high in water content and have a very slow dewatering behavior that requires many years for them to fully...

Fall 2010
A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...

Development of a Waste Rock Simulation Model Including Placement Techniques to Minimize Environmental Impacts of Acid Rock Drainage
DownloadFall 2022
This research aims to develop a model using a systems dynamics approach that can be coupled with TMSim to account for the deposition of waste rock at hard rock mines at the feasibility stage of mine planning. The model includes waste rock placement techniques to minimize the environmental impacts...

This thesis aims to demonstrate the feasibility of using System Dynamics (SD) techniques to develop a transparent, open-source and reproducible model capable of simulating long-term soil water dynamics in a tailings-cap system subject to upward flux from a consolidating tailings substrate. The...

Traditionally, multi-disciplinary modelling exercises involve one discipline mechanistically using the output from a black-box model developed by another discipline. To address this deficiency, the research uses techniques relatively new to the geotechnical community, such as System Dynamics (SD)...

This study investigated the mechanisms driving the dewatering and strength behaviour of polymer amended treated (centrifuged and in-line thickened tailings/ILTT) deep tailings deposits undergoing seasonal weathering dominated by a) multiple freeze-thaw cycles and b) alternating freeze-thaw and...
