Experimental Study on Fire Area Resistance during Mine Fire Period
In order to determine the fire area resistance and its characteristics in the process of tunnel fire accurately,fire area resistance calculation equation is established according to the compressible wind energy balance equation, that fire area resistance mainly depends on the wind temperature and dynamic change through the fire areaand air volume as well.Experiment determined the total ventilation resistance and fire area resistance at various points in the process of coal combustion in the roadway with the help of a similar experiment device.Analysis obtained, fire area resistance will appear from zero to big, than from big to zero with the development, stable combustion and attenuation of the fire; fire area resistance can reach the maximum 71.5 Pa when the air temperature and volume increased to 351.6K and 0.419 m3/s.
