Abstract: Aiming at characteristics of many roadway, complicated ventilation status of a big mineral zone, space figure mutual conversion and ventilation network solution methods were adopted. Ventilation network 3D graphic, simulation data and ventilation network calculation models were set up. Mine ventilation network 3D simulation graphic modeling, automatic dimensioning and ventilation network solution were solved.and the theories and technical guarantee were provided for realization of high level intellectualization and automatization of mine ventilation network 3 D simulation and ventilation network calculation, mine digitalization construction and safe production.

Key words: Mine ventilation network, 3 D simulation, Optimization, Model
