Experimental Study of the Temperature Field Equation in the Leeward Tunnel during Mine Fire Period
According to the principle of heat transfer, the temperature field equation in the leeward tunnel was set up and the experimental device with a ratio of 1:20 was built. When it happened to fire in roadway, the correctness of the temperature field equation can be verified by the experiment. In experiments, the armored thermocouple and color paperless recorder were used to record the temperature of each measuring point. The S-3-300 pitot tube and YJB-2500 compensation micro-manometer were used to determine the wind speed. When the mine roadway fired, the experiment determined the temperature field equation experiment coefficient of Kc. It showed that in the developing phase of the fire Kc = 15 ~ 20, in the stable phase of the fire Kc = 10 ~ 15, in the failing phase of the fire Kc = 20 ~ 25.
