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...

Fall 2016
Chrome carbide samples prepared using submerged arc welding procedures were subjected to physical abrasion testing in a modified machine similar to the ASTM G65 standard, in an investigation of media particle shape contribution to abrasive wear. The primary intent of this study was to determine...

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...

Impacts of a six year old pipeline right of way on Halimolobos virgata (Nutt.) O.E. Schulz (slender mouse ear cress), native dry mixedgrass prairie uplands, and wetlands
DownloadSpring 2016
Reclamation of native prairie ecosystems is of growing importance as they continue to be impacted by anthropogenic disturbances. Since European settlement, Alberta grasslands have declined by 61 %. Grasslands are agriculturally important, act as a carbon sink, and many species depend upon them....

Spring 2024
Multiple data types should be used simultaneously to improve resource estimation models. The multivariate relationship between the data is required. One common approach involves using decorrelation transformation techniques to simplify complex relationships, but this method relies on having...

Investigation of variation in oil sand properties via analysis of seismic and on-board truck data
DownloadFall 2014
The ever increasing size of mining equipment has caused many instability concerns both on board and in the ground underneath. This highlights the need for more in-depth knowledge of variation in the properties of the ground as it has direct influence on the durability and life span of mining...

Learning in Social Action in Contexts of Mining Dispossession: A Critical Case Study of Roșia Montană, Romania
DownloadSpring 2021
Witiw, Taylor Kermit Christopher
Transnational corporations promise win-win development, but extractive projects often deliver dispossession, displacement, impoverishment, environmental degradation, and disrupt social relations in rural localities. These conditions can in turn engender contestation and resistance to...
