Development and application of comprehensive evaluation system for the whole process of mining projects

Rapid economic growth has increased demand for mineral resources, accelerating the development of the mining industry. Mining companies often manage multiple projects simultaneously, facing challenges in performance, cost, and risk management. To address the lack of systematic evaluation frameworks in this domain, this paper establishes a comprehensive evaluation model for the entire process of mining projects. The comprehensive evaluation covers seven aspects: preliminary work, preparation for project implementation, project implementation management, settlement management, final investment cost, post-completion operation, and cost reduction and efficiency improvement. A total of 43 preliminary evaluation indicators were formulated, and the analytic hierarchy process (AHP) was integrated with the fuzzy comprehensive evaluation (FCE) method. The model was applied to an automated control project for a gold mine backfilling station, yielding a final evaluation score of 75.7 that closely aligned with on-site investigation findings, thereby assisting management in formulating and implementing subsequent decisions.
