In order to master thoroughly the impact laws of mine tunnel fire on ventilation system, Fluent software and Ventsim software were used to simulate and compare the same fire power effect respectively, and the change laws and the difference of air flow, wind temperature, toxic and harmful gas concentration and fire resistance distribution along the range were analyzed. The results show that: In a small scope, Fluent simulation is more complex and image, Ventsim simulation is simple but not conforming to reality, and it is more appropriate to use Fluent simulation. In a large range, the simulation results converge, but the Fluent simulation is time-consuming, and Ventsim can be easily solved by Ventsim, then Ventsim model is used. It is more suitable.
