Abstract
We introduce comprehensive fire control measures of 1206 working face in production halts,by using nitrogen injection in goaf,adjusting the ventilation system,reducing the range of pumping gas and so on,the gas emission of goaf decreases to 11.8 m3/min from 15.95 m3/min.At the same time,the CO concentration reduces to 0.
