- W2366680994 abstract "In order to improve the accuracy of safety assessment of goaf collapse,the variable weight theory and fuzzy recognition theory should be used in safety assessment of goaf collapse at the same time.Thus safety assessment model for goaf was established.Minimal cut sets,minimal path sets and the structural importance of each basic events were calculated by qualitative analysis to the fault tree.Three hierarchies assessment index system of the goaf risk was established,and their weight was determined by the analytic hierarchy process and adjusted by the variable weight theory.Relative membership degree of each factor was ascertained.Thus safety assessment model on variable weight theory and fuzzy recognition was constructed and was applied to a certain gypsum mine.The application results show that this model has good maneuverability and has certain reference value for the forecast of goaf collapse risk." @default.
