Thermal Analysis on Fire Disaster Caused by Gas Explosion of Lignite Seam
Abstract：The paper had an analysis on the thermal firing for the fire disaster occurred by lignite seam gas explosion and analyzed the danger of the explosion. From the thermal fire view, a mathematics model was derived and the thermal fire conditions of the secondary fire disaster occurred by the gas explosion were obtained. Within a short period after the gas explosion occurred, the dynamic special heat environment temperature would be higher than the critical fire temperature of the combustibles and thus could cause the secondary fire disaster. In combination with the firing condition and thermal firing condition of the lignite separated products under the special heat environment, a firing analysis was conducted. Once the initial gas density and volume of the lignite seam gas explosion met the three essential factors of the combustibles after the explosion, a thermal firing phenomenon would occur by the explosion.
