Impact of operating conditions on hauler emissions

Hauler emissions, despite the advancement and development of more efficient tier engines over the past 2 decades, remains a challenge for mine operators and original equipment manufacturers. The implications of carbon taxes and minimal to zero emissions by 2030 remains a target out of reach. Understanding the impacts of operating conditions on the ability for a tier engine to operate within the anticipated reduce emission design guidelines is a step on the path to 2030. This paper reports on recent emissions measurements made at an Alberta coal mining operation relative to the operating conditions, in an effort to understand whether the tier engine used is able to cope with the duty expected. These measurements are compared to existing modeled data to establish a predictive emissions performance tool.
