Reliability Evaluation of Six Major Systems of Underground Mine Safety Hedging Based on Matter-element Analysis
In order to accurately evaluate the reliability of the six major systems of underground mine safety hedging,the reliability evaluation model of the six major systems of underground mine safety hedging is established by using the combination weight of game theory and the theory of mine matter-element analy-sis.Firstly,according to the elements of the six major systems of underground mine safety hedging,the reli-ability evaluation index system of 30 evaluation indexes in 6 criterion layers is constructed.Then,by estab-lishing the mine reliability matter-element,the correlation between each index and the reliability grade of the six major systems of underground mine safety hedging is calculated.At the same time,based on the game theory,the subjective and objective weights determined by the entropy method and the analytic hierarchy process are improved.Finally,combined with the actual situation of the mine,the comprehensive correlation between each index to be evaluated and the reliability level of the mine is calculated,and then the reliability level of the six major systems of underground mine safety hedging is determined.After calculation,the reli-ability level of the six major systems of underground mine safety hedging of a phosphate mine is Grade III,which is generally reliable and similar to the evaluation results based on fuzzy comprehensive evaluation method.The research results provide a new idea for safety and reliability evaluation of similar mines.
