Numerical Modeling of Variability Through Mining, Extraction and Tailings Management

Natural resources are an endowment that all Canadians wish to preserve and develop in a sustainable and responsible manner. Of particular importance to Canada and local interest to Alberta are the oil sands of the McMurray Formation. Mining engineering has historically focused on understanding the reserves and economically optimal extraction of those reserves. The management of the material entering processing facilities is important, but the management of the waste streams is of increasing importance. There has to be room for the material in tailings ponds. Concentrations of contaminants, the size distribution of the solids, the strength of the material and other properties must be understood and managed. This calls on a wide cross section of engineering and other disciplines. This research lies in the interdisciplinary region between geoscientific characterization and engineering design: the quantification of geological variability and the transfer of that through the entire process. The focus of this proposal is the calculation of numerical models that are suitable for management of all input and output material streams in a mining operation. Site specific characteristics will be addressed including regulatory requirements, data collection, value of information, and optimization of planning to ensure all constraints are met.
