Abstract: Coal is an important foundation for economy development in our country. Mine safety production is not only the indispensable factors to realizing the healthy growth and the sustainable development in coal mine enterprise, but also the prerequisites to achieving social harmony and ensuring national energy safety in our country. In recent years, the safety situation of China's coal industry is gradually improving, but the situation is still grim compared with developed countries, mainly as follows: higher mortality of millions of tons in our country and large number of accidents and casualties. Combined with the example of Zhengzhou Coal Industry Group, the accident-causing mechanism of coal mine for our country is finally obtained. Based on this logical framework of accident-causing mechanism, the coal mine safety evaluation indexes system are determined with the use of literature research and information entropy. Then, through the combination of fuzzy theory and neural network models, a new ideas is proposed for the safety evaluation of coal industry of this a complex system.
