Effects of Cyclical Load Conditions on Wear Rate and Wear Scar in a Modified ASTM G65 Abrasion Test
DownloadSpring 2016
Wear is an incredibly complicated phenomenon that can occur in many different forms, through a number of modes, facilitated by a variety of mechanisms. Surface mining operations are particularly afflicted by abrasive wear; principally during the excavation process. Shovel geometry has been...

Electric Rope Shovel Operation Enhancements, Understanding and Modelling the Impact of The Operator
DownloadSpring 2021
The loading and haulage system is considered a prominent part of a surface mine operation. Improving the system enhances the productivity and economics of an operation to a great extent. Operators play a critical role in the mine overall performance and production. Autonomous truck fleets have...

Enhanced Geologic Modeling with Data-Driven Training Images for Improved Resources and Recoverable Reserves
DownloadFall 2015
Deterministic geologic modeling methods accurately characterize large-scale continuous features of geological phenomena, but often fail in reproducing their inherent short-scale variability. The opposite is the case with stochastic methods that lack large-scale continuity yet contain reasonable...

A numerical reservoir model is the result of studies whose main objective is to describe the dynamic behaviour of a hydrocarbon reservoir for predicting its future performance under different development and production strategies. Reservoir models are built with uncertain parameters. The...

Factors driving switches in the primary producer communities of shallow lakes of the Boreal Plains, Alberta, Canada
DownloadFall 2012
The mechanisms that contribute to the frequent switching of primary producer communities in shallow lakes on the Boreal Plains of Alberta, Canada were explored. The lakes tend to be clear and macrophyte-rich (61% of lakes) or turbid and phytoplankton-rich (30% of lakes). The study is based on...

From Drought to Deluge: Implications of variable hydrologic connectivity on lake ecosystem functions in the Boreal Plains of Western Canada
DownloadFall 2021
Presence and functions of lakes are dependent on hydrological connectivity to the terrestrial landscape. Inter-annual wet-dry periods, and their amplification through climate change, can influence hydrological connectivity and affect the delivery of water and solutes from various terrestrial...

Geostatistical modeling used to focus on the grade of the main commodity or metal being mined and sold for profit. As mining has developed, the metallurgical characteristics of the rock have become important. Geometallurgy tests are developed to understand the processing characteristics of the...

In general, less than one billionth of the volume of a deposit is sampled before production decisions. The grades and other rock properties are estimated in the unsampled volume. The success of a mine is dependent on accurate grade control. The grade control process establishes the final planned...

A challenge in petroleum geostatistics is the application of modeling algorithms such as Gaussian simulation to unstructured grids that are being used for flow simulation. Geostatistical modeling is typically applied on a fine scale regular grid and then upscaled to the unstructured grid. This...
