An integrated framework for maintenance activities management in mining industry

This work focuses on maintenance in the mining industry through a given case of study. In general, the maintenance cost may represent up to 40 – 50 percent of the total operating cost and especially in phosphate mines [1]. The pressure to reduce this cost is permanent and one of the ways of optimization is to focus on maintenance data management during the planning and execution. In fact, transparency and real-time information for the stakeholders of maintenance activities are important in the mining industry context. Given the complexity of the problem, we decided to apply the system engineering (SE) methodology using the SysML modeling language to contribute to better management of maintenance workshop activities. The proposed models have been verified based upon the Moroccan phosphate mine case. The utility of the proposed solutions can clearly be observed through this case of study.
