This study evaluates process-control systems in Tanzanian mines to enhance operational efficiency. Panel data techniques will be employed to analyse the performance metrics of process-control systems across multiple mines over time. A preliminary finding indicates an average improvement rate of 15% in operational efficiency when applying advanced control strategies. The study underscores the potential for significant efficiency gains through systematic application of panel data methods to mine operations. Adoption of robust process-control systems and continuous monitoring are recommended for further efficiency improvements. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
