Experimental Research on the Stability of Airflow in Diagonal Network during Fire
In order to study the influence of tunnel fire on the airflow stability in diagonal network of single diagonal network ventilation, according to the principle of similitude air supply system of 4101 working face of Huhewusu was taken for research object. In a proportion of 1:20, simulation device for angle connection roadway was established. By means of this simulation device and the method of experimental simulation, change law of the air volume and wind direction of diagonal branch in single diagonal network was studied. The results showed that in a particular period of mine fire, air volume decreased in fire roadway and windage increased; air volume in diagonal branch decreased and with the process of fire the wind direction would change. After the change of wind direction, with the changing of fire scale the reverse air volume would show the same changing process.
