Spring 2011
This study was part of the development of an ice jam flood forecasting system for Hay River, NWT. 2-D numerical models were used to simulate ice processes in an effort to predict ice jam formation. A summer survey was conducted to finalize the bathymetry of the Hay River Delta. Observations were...

Accounting for non-stationarity via hyper-dimensional translation of the domain in geostatistical modeling
DownloadFall 2009
Medium and short term mine planning require models of mineral deposits that account for internal geological structures that permit scheduling of mine production at a weekly and monthly production periods. Modified kriging estimation techniques are used for accounting for such geologic structures....

An Examination of the Effect of Diluent on Microbial Dynamics in Oil Sands Tailings and the Mechanistic Insight on Carbon Dioxide-mediated Turbidity Reduction in Oil Sands Surface Water
DownloadFall 2019
Oil sands fluid fine tailings (FFT) are comprised of sand, silt, clay, residual organics, salt, trace metals and process-affected water (OSPW). In order to accommodate and remediate large amounts of FFT, a full-scale demonstration pit lake, where FFT was capped with a mixture of OSPW and fresh...

An Integrated Optimization Model for Strategic Open-Pit Mine Planning and Tailings Management
DownloadFall 2014
Badiozamani Tari Nazari, Mohammad Mahdi
A strategic mine planning model determines the best order of extraction and destination of material over the mine-life, in a way that maximizes the net present value of the produced minerals. In case of oil sands open-pit mining, further processing of the extracted oil sands generates massive...

Application of coagulation-flocculation process for treating oil sands process-affected water
DownloadFall 2011
Oil Sands Process-Affected Water (OSPW) is generated from oil sands operation processes such as mining, extraction, and upgrading. Currently, accumulated OSPW is temporarily stored in tailings ponds which are toxic to the environment and must be treated for either reuse or safe discharge in the...

Fall 2014
The extraction of bitumen from oil sands in Alberta, Canada, leads to the creation of tailings that are contained in lake-sized ponds under zero discharge policy. Stratification of tailings over time leads to the formation of mature fine tailings (MFT), an oil based emulsion containing residual...

Spring 2014
With the trend of global urbanization, underground space is being more and more exploited. To fulfill the need of sustainable development of underground space, it is necessary to well document the as-built positions of the facilities we have built. In the current practice, the as-built models are...

Spring 2016
A study was implemented to evaluate different alternatives of soil cover systems for the closure of approximately 1539 Mt of waste rock at the Antamina Mine (Peru). The soil covers were designed to limit water percolation to the underlying waste rock, by combining a store/release and low...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Bioremediation of oil sands process affected water sourced naphthenic acid fraction compounds
DownloadFall 2020
Current development of Alberta’s oil sands region requires large volumes of water, leading to an abundance of oil sands process affected water (OSPW). OSPW contains naphthenic acid fraction compounds (NAFCs) which have been found to contribute extensively to OSPW toxicity. Degradation of this...
