Abstract
To provide a theoretical basis for application of inert gas injection measures on the mine fire disaster relief, the paper establish mathematical model for the influence of inert gas injection to fire zone’s flow field, and the FLUENT software is used to carry out numerical simulation, at last, the simulation results are compared with the experimental results. The result shows that, while the velocity of inert gas is in low, the gas layer of closed fire zone is still existing; its verified the effect that inert gas can promote the front gas layer and dilution the back mixed gas layer; what’s more, the numerical simulation of experiments verify the reliability of the results inert gas injection. The results have great significance on mastering the fire zone’s state change when injecting the inert gas, forecasting the explosion suppression effects and giving a good guide on using the inert gas to suppress the fire zone’s explosion.
