Fuzzy Comprehensive Evaluation For Huo Shiju Coal Mine Ventilation Based On AHP

Coal mine accidents not only cause loss of property in our country,and still can cause personal injury.For mine disaster plays a decisive factor is the stand or fall of mine ventilation system.Therefore,to evaluate mine ventilation system is particularly important,timely to evaluate mine ventilation system can find the problems in mine ventilation,and then optimize the transformation,to prevent mine accidents.Based on the basic theory of fuzzy mathematics theory,AHP and multi-level fuzzy comprehensive evaluation theory analysis and research,draw lessons from the ideas of forefathers' research innovation,establish the mine safety evaluation model based on improved analytic hierarchy process,determining the weight of each index and index membership degree form a comprehensive evaluation method.Mainly from the quantity and downhole conditions of rationality,efficiency of ventilation network and facilities,ventilation,power reliability and the reliability of the ventilation system monitoring four aspects to analysis,finally combined with field test data collected from flint tsui coal mine application,the evaluation results for the secondary,the reliable level.The evaluation method achieved good effect in practical application,improving the overall level of flint tsui coal mine ventilation system.
