Abstract: Based on analysis of data mining technology,rough set theory,fuzzy logic and neural networks algorithm,the paper proposed a design scheme of safety information management model of coal mine based on data mining.The model uses Web server registration technology and XML data composition technology to form terminal database,adopts rough set theory and fuzzy logic and neural networks algorithm of data mining technology to form terminal data warehouse,and analyzes,manages and maintains terminal data warehouse in an unified may.The model improves efficiency of safety information management of coal mine effectively.
