Experimental Study on the Change of Air Volume in Roadway During Mine Fire Period
According to the theory of fluid similar, the similar experimental device was built, which to the 4104 main transport crossheading, auxiliary transport crossheading and contact roadway in Huhewusu for the physical prototype as the ratio of 1:20.Determined the air volume during fire with the device, and the results showed that; air volume decreased and maximum decline was - 15.20％ in main transport crossheading, at the same time, air volume in auxiliary transport crossheading and contact roadway which near the fire zone increased and maximum increases was 15.57％ while the fire was on main transport crossheading. From the development and stable phase to the decay phase, the air volume was divided into two types in each branch, one reduced to the minimum value firstly and then gradually increased to normal; the other one increased to the maximum value firstly and then gradually decreased to normal.
