One of the most important influencing factors on the economy of mines with surface and underground exploitation is the correct choice of haulage technology of ore and waste.
The paper analyzes the haulage of ore and waste in the Lead and Zinc Mine “Sase” Srebrenica and determines the optimal haulage length on the four excavation blocks for the application of the new haulage system by using the mine trucks from the aspect of set criteria, increasing capacity and reducing haulage costs through the techno – economic analysis and optimization.The optimal haulage length is determined through the calculations of the loader capacity and the possible choice of the truck
depending on the stated criteria.
Key words: underground production system, optimal haulage length, combined haulage, operating costs
