The simulation research about the smoke control effect of the air curtain for mine gob fire
To take spontaneous combustion of coal goaf legacy in a mine 3232(3) working face as example in this paper.To the fire smoke spread to return airway in gob, by using FDS for setting up different working conditions of air curtain in the upper corner of stope face.The change law of parameters such as the temperature,visibility and so on is simulated, to the application of air curtain technology in mine fire period has carried on the preliminary exploration.The results show that 3232(3) working face spontaneous combustion of coal mine goaf, the effect of air curtain for preventing smoke can obtain a better consequence when the supply speed of air curtain is set to 2~3 m/s.
