Technologies of open the fired zone of 1504 working surface in Jiaxin Coalmine safely

摘要：

　　This paper introduces the case of firing of 1504 working surface with high content of gas and facile spontaneous combustion of coal seam of No.15 in Jiaxin Coalmine.By a large number of investigation and theoretical analysis on the fire field,all factors causing the fire in 1504 working surface were found out and the position of fired area of the goaf was determined.The gas inside fired area were monitored by a series of means.Based on the truth that the fire have been extinguished,a reasonable plan for fire zone opening is proposed,according to the fire position and factors causing the fire,to ensure the safe opening of the fired area of 1504 working surface.
