Identification of Critical Components of Underground Mine Conveyors for Maintenance Optimization: Case of the Gara Underground Mine

The development of a maintenance plan for conveyors of the Gara underground mine represents a major challenge for improving the efficiency of ore transport operations. This work aims to develop a methodical and structured approach for the implementation of a maintenance plan, adapted to the specificities of conveyors used in an underground environment. With a view to developing a preventive and corrective maintenance plan for the mine conveyors, reducing downtime and optimizing the performance and life of the facilities. Specifically, we will identify critical components, define the necessary maintenance tasks. The development of this plan aims to optimize the performance of the conveyors while controlling the costs related to failures. The methodology includes the analysis of technical specifications, the identification of critical components using PARETO diagrams. This project shows how crucial it is to adopt an organized approach for the maintenance of conveyors in a mining context. A well-developed maintenance plan can significantly improve the performance and durability of equipment. The most critical components were the rollers.
