Abstract: In view of problems that production management methods in some coal mines are lagging behind, management cannot be quantified, control cannot be programmed and management cannot be effective in preventing overall accidents, a design scheme of safety quantitative management system based on FAT model was proposed. The system makes data to be quantified which involves mine safety and uses FAT analysis model to realize dynamic security assessment of all locations of coal mine. The actual application in a number of coal mines showed that the system can effectively promote standardization and informatization of coal mine safety management and improve coal mine safety management level.
