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...

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...

The focus of the research presented here was to directly measure actual evaporation rates from a tailings surface using a micrometeorological technique known as the eddy covariance method. Depending on the results, it would be determined whether current drying models need to be calibrated with...

This thesis explores the development and preliminary operation of a new test method for roller and roller path arrangements on ultra-class mining shovels. The lack of existing lab-scale test methods discourage significant change, and restrict the development of the roller and roller path to minor...
