Comprehensive Evaluation Of Jinchuan Coal Mine In Bijie City, Guizhou Province

Beginning of this article pointed out that China’s coal industry occupies an importantposition in the national economy，also pointed out that the ventilation system plays a veryimportant role in the process of coal’s safe production. Evaluation analysis of the ventilationsystem is one of the important means to improve mine safety issues， since most safetyassessment theoretical stage has not yet been fully applied to a complex system of coal mine，so the research of coal mine ventilation system’s safety evaluation is imperative.A number of factors of mine ventilation system have fuzzy， gray and multilevelnature of the characteristic，This paper studies the fuzzy comprehensive analysis，and usingfuzzy analysis and gray entropy model of mine ventilation system to study comprehensiveevaluation method. Jinchuan coal mine is using by the paper for an example，study on theproblems of ventilation system in the safety evaluation which by the use of systems science，decision science theory and methods， the paper discussed for mine ventilation safetyevaluation index system of the mine. Finally put forward the correspondingcountermeasures and suggestions for rectification of the mine’s ventilation system， therebysignificantly improving the efficiency and accuracy of the safety evaluation in theventilation system of Jinchuan coal mine. While the use of advanced evaluation anddecision theory.
