| Abstract: | Basing on the theory of two-phase flow of gas and solid, and the characteristics of coal mine driving working face, using the discrete phase models of computational fluid mechanics to simulate the dust concentration during the ventilation process of coal drift driving with exhaust ventilation. Summarize the distributing and the rule of movement of the dust concentration. |
