Abstract: In view of the low efficiency in traditional production scheduling system of open-pit mine, the authors have developed a practical and efficient production scheduling system for  open-pit mines by adopting global positioning system(GPS) and combining the computer network technology，digital communication system, optimization theory and management information system, which can realize the management of traveling equipment through the functions such as acquisition and dynamic display of real-time data, state analysis of equipment, determination of dispatching plan, data processing, data inquire, statistics and generation, etc. It has solved the key problems including ore blending, GPS positioning error and traveling equipment positioning and been successfully applied in the practice, which is of great significance to the realization of open-pit mine automatic management.

Key words: GPS, Open-pit mine, Traveling equipment, Dispatching
