Abstract: In order to solve problems that existing safety training system of coal mine is independent of welling attendance system and has poor training effect, the paper proposed a design scheme of pre-post training and testing system for coal miner, and gave structure, working process and main functions of the system. The system uses mixed development mode of B/S and C/S, integrates safety quantification management system and iris attendance system through unified portal management mode, and adopts welling management method of examination before attendance, namely the miners only passing examination can go underground. The application showed that the system improves initiative of miners for learning safety rules and validity of safety training of coal mine, which provides a new method of safety management and training of coal mine.
