The chal­lenge

In the pits we must care­ful­ly bal­ance the num­ber of trucks assigned to each Shov­el (or “Load­ing Unit”). If the Shov­el does not have enough Haul Trucks, it can­not be ful­ly pro­duc­tive. If it has too many, then the Haul Trucks are not productive.
 
Rosebel’s Dis­patch Office is where this bal­ance of equip­ment is mea­sured. The cycle of each Haul Truck is mon­i­tored in real-time from the loca­tion where it is loaded, the route it trav­els (roads and ramps), where it is dump­ing, and the return path to the next load. Dis­patch­ers work with Mine Oper­a­tions and Mine Plan­ning to opti­mize these move­ments in a way that reduces traf­fic and wait­ing time for both fleets: the Load­ing Units and the Haul Trucks.
 
Oper­a­tors, Super­vi­sors and Gen­er­al Fore­men com­mu­ni­cate with Dis­patch­ers through­out the shift to share infor­ma­tion on road con­di­tions, vis­i­bil­i­ty and equip­ment main­te­nance con­sid­er­a­tions. Orches­trat­ing this bal­ance of fleets in a safe and effi­cient man­ner is tru­ly a Team effort
