The Research of Coal Hazard Evaluation Based on Fuzzy Probability

The hazard assessment is the fundamental work of safety risk management work. Hazard investigation and defensive are important for preventing and controlling accidents. Coals as a complex system, its hazards have the randomness and fuzziness, which belongs to the category of fuzzy probability. Using the fuzzy synthetic evaluation method of classic study will produce a reasonable result. To introduce fuzzy probability theory into coal hazard assessment and analysis of the coal hazard will solve such problems with random uncertainties. This paper shows that the method is reasonable and reliable.
