Mine fleet management refers to the systematic planning, allocation, tracking, maintenance scheduling, and performance optimization of the entire mobile equipment fleet operating within a mine site, including haul trucks, excavators, loaders, drills, graders, water trucks, and auxiliary vehicles. In bauxite, gold, iron ore, and diamond mining, the mobile fleet represents the largest single capital investment after the processing plant, and its effective management is directly linked to mine productivity, safety performance, and unit cost control.
Modern mine fleet management systems (FMS) are sophisticated software platforms that receive real-time positional data from GPS-equipped machines, process this information through dispatch algorithms, and issue instructions to operators via in-cab displays to optimize truck assignments, minimize queuing at shovels and dumps, and maximize payload utilization. Leading FMS platforms used in large-scale iron ore and bauxite mines include Wenco, Modular Mining's DISPATCH, and Caterpillar's MineStar Command, which can manage fleets of several hundred machines simultaneously.
Fleet management encompasses several interrelated disciplines. Truck dispatch optimization minimizes empty travel and queue times through dynamic routing and shovel-truck matching algorithms. Payload monitoring systems fitted to rear-axle strut pressure sensors ensure trucks are consistently loaded to their optimal payload, preventing overloading that accelerates wear and underloading that reduces productivity. Machine health monitoring uses onboard engine management systems, oil analysis, and vibration sensors to predict component failures before they occur, enabling condition-based maintenance that reduces unplanned downtime.
In gold and diamond underground mines, fleet management adapts to the constrained geometry of drives and stopes, where smaller machines such as low-profile loaders (LHDs) and haul trucks operate. Collision avoidance systems using radar, proximity detection, and ultra-wideband radio positioning are increasingly integrated into underground fleet management to prevent collisions in confined, low-visibility environments.
