| Abstract: |
| In this paper, we set up the evaluation index system for spontaneous mine fire on the basis of the analysis of influential factors of the fire risk. Combining fuzzy mathematics theory with correlation degree theory in grey mathematics, the fuzzy evaluated model for mine inner fire is established. Using this model, we evaluate the Xinyuan Mine of Zaozhuang Mining Corporation, analyze the main existing problems and put forward countermeasures. |
