Abstract
A mine’s haul road network has a large influence upon the success of a mine, and aside from occasional visual inspections, a significant number of mines put little emphasis on monitoring the condition of haul surfaces. The opportunity exists for a haul road benchmarking system, which can be achieved utilizing truck suspension cylinder data that is readily available to a mining operation. Understanding the interaction between road profiles and haul trucks can provide valuable information on the stress imposed on the truck by large road defects, and be utilized as a condition monitoring tool for maintenance. Applying novel analyses to g-level forces generated by suspension cylinders can assist mine planners diagnose the cause of potential truck damaging road conditions, to prioritize where to dispatch road maintenance support equipment.
