In order to increase equipment reliability, decrease unscheduled downtime, and optimise maintenance costs, this study assessed Risk-Based Maintenance (RBM) strategies for mechanical equipment in mining operations. A mixed-method research design was used, which included semi-structured interviews with maintenance staff at specific Rungta Mines Limited mining units, Failure Mode and Effect Analysis (FMEA), Risk Priority Number (RPN) computations, and performance metric evaluations (MTBF, MTTR, availability, and cost). By identifying high-risk components and facilitating proactive interventions, RBM considerably outperformed conventional Corrective and Preventive Maintenance strategies, according to data analysis. Improved availability, shorter repair times, and lower maintenance costs were demonstrated by equipment running under RBM, and qualitative feedback confirmed that staff members were more operationally confident and risk-aware. The results clearly show that, in the mining context, RBM is a more sustainable and successful maintenance approach, meeting all research goals and providing insightful information for strategic maintenance planning in heavy industrial settings.
