Study on the Method of Risk Fuzzy Sequence to Hazards of Gas Explosion Accidents in Heading

摘要

Based on Fuzzy theory, the structural model of risk assessment is established by analyzing hazards of gas explosion accidents in alley. Hazards of gas explosion accidents in heading are systematically researched by applying the fuzzy risk assessment. As sequence of accident risk is of character of relativity and fuzzy, the authors calculate relative belonging of risk for gas explosion accidents applying the concept of weight distance and belonging. Furthermore, to demonstrate the degree of accident risk effectively, the fuzzy sequence method for hazards of gas explosion accidents in alley is put forward in the paper.
