Research on smoke flow law and effective control schemes of fire in mine roadway fires
When a mine roadway fire occurs,a three-dimensional model of mine ventilation was constructed based on the 3D mine simu-lation platform.Combined with the three models of fire wind flow temperature,concentration and fire wind pressure,the dynamic spread process and principle of fire wind flow were studied.By establishing the physical model of regulation,the control scheme was simulated by Pyrosim software,and the experiment was carried out by using the small-size ventilation system to verify the feasibility of the control scheme.Combined with the three-dimensional ventilation system model of Bayangaole Coal Mine in Inner Mongolia,the flue gas flow when the fire occurs in different positions was simulated,and the smoke flow path was effectively controlled by taking the flue gas spread in the main transportation roadway as an example,so that the fire flue gas can be discharged from the mine in the shortest time to mini-mize the harm caused by the fire.
