Optimization of GPS on Track-Dozers at a Large Mining Operation

Janet A. Flinn and Scott M. Shields

Abstract:	Implementation and optimization of GPS on track-dozers can have a significant impact on mining operation productivity. GPS utilization can be optimized through proper system management, where track-dozers are allocated to work on roads, special projects, stockpiles, property boundaries, or drilling and blasting applications, as economic and safety conditions necessitate. The “hot swapping” capabilities of the GPS units allow quick and proper placement of GPS resources. Prioritization is necessary to achieve reduced operating costs at Phelps Dodge’s Morenci copper mine in southeastern Arizona, where over 840,000 tons of rock is mined each day. The mine currently has six GPS units for use on a fleet of over 31 track-dozers. Capital expenditure for the six systems has been amortized approximately five months following implementation.
