Computer-based dispatching in open-pit truck haulage operations yields many benefits of current interest to mine management. The key tangible benefit is a substantial productivity increase with a given fleet of equipment or, alternately, a significant reduction in equipment required to meet production quotas. Other tangible benefits in mines with concurrent operating objectives include minimizing rehandle, meeting several blending constraints simultaneously, and ensuring a target plant feed rate. Intangible benefits include production forecasting, performance comparisons of trucks or shovels of different manufacture, and extensive on-line report generation. Recent advances in mini- and micro-computer hardware and software and solid state electronics permit design and implementation of system features not feasible a few years ago. This paper discusses system aspects with emphasis on dispatching algorithms needed to meet concurrent objectives.
