Research on Optimization of Ventilation System of Wanglou Coal Mine Based on Ventsim
Wanglou coal mine has the characteristics of the long-distance ventilation system in,especially with the mining of the seven mining area,the resistance distribution of the ventilation system is uneven,and the problem of poor stability of the ventilation system is becoming more and more serious.On the basis of obtaining the basic ventilation parameters,Ventsim is used to establish a 3D visual model of the mine,propose three optimization schemes,and predict the expected effect of each scheme through the model.At the same time,the optimization model of mine ventilation system scheme based on game theory combination weighted weighted rank ratio method is proposed,and the connection of special return air lane in seven mining area is the optimal scheme.The field practice shows that the operation rate of mine fan increases,the resistance distribution tends to be reasonable,and the scheme optimization model has reference significance for the same type.
