Accelerating Polymer Degradation to Explore Potential Long Term Geotechnical Behaviour of Oil Sands Fine Tailings
DownloadFall 2021
Many tailings’ technologies used in the Athabasca oil sands require the use of chemical amendments such as synthetic flocculants to densify tailings by releasing water. It is anticipated that the synthetic flocculants will eventually degrade with time leaving only a mineral soil structure behind....

Fall 2024
Reclamation of oil sands mines in northern Alberta presents a significant challenge for mine operators, particularly the reclamation of tailings deposits that are produced by the mine waste stream. A proposed approach to reclaiming tailings deposits as upland or wetland landforms is capping which...

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...

Freezing Characteristics of Mine Waste Tailings and their Relation to Unsaturated Soil Properties
DownloadSpring 2018
The study investigated the feasibility of using the soil freezing characteristic curve (SFCC) to estimate the soil water characteristic curve (SWCC) in mine waste tailings as an alternative to traditional SWCC testing. Traditional SWCC tests are challenging and time-consuming to conduct, taking...

Spring 2021
Reclamation of oil sands fluid fine tailings (FFT) is a challenge for mine operators in Alberta because of their high water content and slow self-weight dewatering. Chemical additives, including polymer flocculants, are used by operators as a treatment technology to reduce volumes and increase...

Influence of Fill Scheme on Oil Sands Tailings Consolidation Modelling in a Geotechnical Centrifuge
DownloadSpring 2021
A series of geotechnical centrifuge modelling experiments were conducted on a kaolinite slurry and treated fluid fine tailings (FFT) material to assess consolidation behaviour. Consolidation modelling for both materials was conducted using both a single and layered fill scheme, and the results...

Optimization of a Cover Design for Acid Rock Drainage Prevention in a Permafrost Environment
DownloadFall 2021
The extraction of sulfide-bearing waste rock can contribute to the generation of acid rock drainage (ARD). ARD is the effluent generated due to the oxidation of sulfide minerals which can be toxic to the receiving environment. Waste rock material which contains potentially acid-generating (PAG)...

Risk Management for Tailings Dam Safety: Considerations for Long-term and Post-closure Timelines
DownloadFall 2022
Post-closure tailings dams are expected to remain on mine sites in perpetuity following mine closure. Combined with the lack of knowledge regarding how tailings dams will evolve over time, these long-time frames necessitate the development of risk management practices. The purpose of this...
