Formatted abstract
Open cut mining operations are constantly looking for ways to optimise production by improving the efficiency of truck and shovel fleets. DISPATCH is a GPS based mine control software program that aims at optimising operations by reducing truck and shovel waiting times by maintaining a constant and distributed truck flow. This research project investigates a current DISPATCH system in operation at Alumbrera Mine and looks at ways to improve its performance. The current issues with the DISPATCH system are investigated and a number of research tasks completed in order to address these issues. These research tasks were based on:

• Truck Speeds
• Distance Calculations
• Truck and Shovel Waiting Times
• GPS Availability at Alumbrera

Average real time truck speeds have been calculated relative to the load being hauled and the grade of the road. These speeds have been used to generate distance factors, required for the development of the ‘Equivalent Distance’ concept. Equivalent distance is the horizontal distance that the same truck would travel in a set period of time if it wasn’t travelling on a ramp. These equivalent distance calculations have been used to generate key performance indicators in the form of T*KmEQUIV/Hr. The daily DISPATCH data can be used to generate these KPIs so that the production rates of the truck fleet can be monitored on a day by day basis. The next task completed looks at the truck and shovel queuing times recorded by DISPATCH. A number of methods to monitor and reduce these operating inefficiencies are explained. Finally the availability of the DISPATCH system as a result of satellite visibility is investigated along with the effects this is having on operations. A number of methods for improving satellite visibility are looked at and recommendations given.

It was found that the operation at Alumbrera mine was overtrucked and by reducing the number of trucks the operating time wasted due to queuing can be reduced significantly. It was also discovered that Alumbrera has periods of poor satellite visibility which can be improved by installing pseudolites once a cost benefit analysis has been conducted.
