Abstract: The development of Mine Expert System is based on the development of productive forces, a conservation-minded society, and productivity improvement.Firstly, the application situation of domestic and foreign mine expert system is represented in the paper which is used in the mining system design decision-making, optimization, production and evaluation system, the production of information technology management, fault diagnosis and prediction, disaster prediction and prevention.The algorithm mainly includes fuzzy logic and neural network. The problem of current Mine Expert System also is analyzed in the paper and the development way is given finally.
