Application of Risk Ranking Method Based on Linguistic Scale in Coal Mine Safety Management

In order to solve abstract fuzzy language problem in practice and easily compare the various safety risks, we used fuzzy analytic hierarchy process based on linguistic variable to quantify subjective evaluation twice to obtain the weights of relative importance and relative frequency of occurrence from the starting point of management and operating personnel, and then got the risk ranking of safety risk. It provided the effective measurement reference for coal safety management work.
