The reuse performance of protective masks in metal mine work environments was systematically analyzed. By considering the special nature of the mine work environment and the protection requirements, the commonly used materials and structures of protective masks for mines were analyzed. The feasibility, challenges, and comprehensive evaluation index system of reuse were mainly discussed. The results show that reusable masks have significantly better economic and environmental benefits than disposable masks. However, the filter elements or filter cotton need to be replaced regularly, and the mask body needs to be cleaned and maintained frequently to ensure the filtration efficiency and sealing performance. The evaluation system is centered on protective performance, followed by usage performance and then hygiene and safety performance. Future research focuses on the development of long‐lasting and low‐resistance filtering materials, intelligent maintenance reminder technology for masks, and the construction of dynamic evaluation models based on actual working conditions. The research provides a scientific basis for mine workers to choose and maintain reusable masks, helps to reduce the risk of pneumoconiosis, and promotes the development of protective equipment for mines towards efficient, economic, and sustainable directions.
