according to the actual situation of Liangbaosi coal mine, the problems of the spontaneous combustion of coal and characteristics of spatial coal spontanous ifre is analyzed. The technology of big lfow of liquid nitrogen inerting mined-out area and gas displacement is proposed and practiced. aiming at the mechanism of nitrogen for gas ifre extinguishing is analyzed. The technology and method, inerting index of nitrogen for ifre prevention is determined. Thus, the coal spontaneous combustion hazards can be controlled effectively.
