Study On Analysis And Evaluation For Ventilation System Of Honglin Mine In Shenyang

Rational ventilation system is the prerequisite of good ventilating that has an impact on the coal mine production and economic benefit. So it is necessary to study the technologies supporting for DSS, which are used for deciding whether ventilation system is in a steady and safe state, also reflecting the state of ventilation system in quantitative and intuitive manner. This research could have great value in theory and practical significance.Stability analysis of ventilation system based on sensitivity theory is introduced to the paper, then, while sensitivity numerical analysis is carried out. Then automatic identification technology of diagonal structures under undirected graph is applied to finding diagonal structures in Honglin mine. Drawing and analyzing ventilation network characteristic graph come to the end. From three aspects above, the analysis and evaluation is performed on ventilation system of Honglin mine in Shenyang. Subsequently a comprehensive analysis of the stability is presented. It is proved that the three theory above and technologies could provide more favorable technical supports of DSS.
