- W2358674860 abstract "In order to assess blocking risk of filling pipe system in deep mine,a comprehensive index model of filling pipeline blocking was established on the basis of the entropy theory.Regarding Longshou mine of Jinchuan company,Dahongshan copper mine,Hedong gold mine and Xincheng gold mine as the evaluation objects for blocking risk of filling pipeline,ten evaluation indicators were selected as the discriminant index of the comprehensive model.The corresponding matrix was established according to the in-situ data of the mines and the three evaluation standard of blocking risk of filling pipelines.The entropy theory was used to calculate the weight of each discriminant index,and the predictive blocking risk of filling pipelines was finally obtained and sorted using the rule of comprehensive index model.The results show that the blocking risk of Longshou mine of Jinchuan company is lower than level Ⅱ,and the blocking risk of Hedong gold mine,Xincheng gold mine and Dahongshan copper mine is lower than level Ⅲ.It was followed that the blocking risk of filling pipeline of Longshou mine of Jinchuan company is significantly greater than that of the rest three mines,and the difference among the blocking risk of filling pipeline of the other three mines is small.The comprehensive index model based on the entropy theory can reflect the distance between the sample and the evaluation standard,and the evaluation is objective,reasonable,and practicable." @default.
