Abstract: This paper simply introduced the software-Avwine. Taking Kongzhuang Colliery as an example， Avwine was applied to resolving mine ventilation network. After introducing resolution algorithm in detail， resolution results and their errors were analyzed. The errors between resolution results and field data were below 5%. This showed that Avwine could fast and precisely simulate mine ventilation system and simulation data could be as reference for adjusting ventilation network.
