Abstract

This study aims to optimise the fuel consumption of Caterpillar 785D off-highway trucks as used by the project sponsor at an open cut coal mining operation in Queensland, Australia.

This was achieved by:
- Researching mine design and operational factors influencing fuel consumption of off-highway trucks
- Identifying variables and haul road design scenarios relevant to the project sponsor’s particular operation
- Creating a data collection program to obtain and combine relevant condition monitoring data from multiple sources
- Analysing the data for variations in fuel consumption
- Quantifying fuel consumption in different haul road scenarios

Fuel consumption rates were found for three scenarios, ascending ramps, stop-start driving and idling. Mining engineers can use these quantities to predict fuel costs incurred by various ramp grades and lengths, truck queuing, intersections and other similar road features. Fuel costs can be compared to construction and production costs to determine optimal road designs. An additional tool was created to assist with the calculation of fuel costs over the life of a ramp. This tool demonstrates how these costs are affected by ramp grade.

The methodology could be expanded to other truck models or operations in the future. In addition to optimising fuel consumption, condition monitoring data could also be used to optimise other production, design or maintenance tasks.
