  • In this paper, Tashan Coal mine is taken as the research subject and a new ventilation method is put forward. Then, based on the non-linear computation model of air-flow, this thesis, using computation software of Comsol, will make an analysis of the flowing rules under different quantity of air intake. The result shows that when the air intake has the same quantity in two lanes, the vortex will be created in working face, with a air velocity of 9 m/s. In such case, gas accumulation will take place and flowing states of air-flow can be presented in a normal distribution. When the air intake has the different quantity in two lanes,gas accuniulation will not be produced and the air velocity reaches 4.7 m/s so that the gas can be completely diluted. And also, the flowing states are non-stable. Therefore, different quantity of air intake contributes to the gas dilution.
