Dynamic imitation study on fire effect in coal mine

The unsteady state mathematics model is established by applying the theory of the hydrodynamics, combustion, energetics after the fire in coal mine. The dynamic imitation software of the polluted lane is made on the base of it, and the method solve the equations is discussed. Finally the Dalong Mines ventilation system of Tiefa Mining Bureau is imitated by the software, it can conclude: the polluted lanes are only the lanes as 40～46 when it is 8 min after the fire, but the fire pressure becomes bigger and the smoke becomes more thick with the time development, the polluted lanes will be the lanes 32～46 when it is 25 min. It is referenced valuable for the making policy and directing in rescue by imitating the polluted result of fire in each moment.
