Improving the efficiency of haulage systems is one of the more significant challenges in mining engineering, and is the subject of many research projects undertaken in both academia and industry. For mining, haulage systems must be designed to be as efficient as possible to minimise haulage costs, improve profitability, and increase the total mine value.
Haulage system inefficiency is typically derived from inadequate engineering, which results in poor haul road design, machinery stand-by and downtime, and circuit traffic. Haulage costs can be some of the largest in the mining system. In various case studies, it was found that material transportation represents 50 per cent of the operating costs of a surface mine.
One of the most effective components of haulage system efficiency is the movement of trucks, where these machines consume a significant amount of fuel and play a central role in mine productivity and efficiency. Many factors affect the efficiency of haul trucks, such as the accuracy of dispatching systems, payload, truck speed, haul road condition, road design, traffic layout, fuel quality, weather conditions and drivers’ skill.
