Abstract

In the mining process of 4405 working face, spontaneous combustion of remaining coal is prevented by injecting nitrogen to goaf through buring pipe and continuous injecting nitrogen. Meanwhile, pre-bury beam tubes in the goaf and measure the gas concentration of each measuring point before and after continuous nitrogen injection. Combined with residual coal spontaneous combustion theory in goaf, the distribution variations of "Three Zones"of goaf spontaneous combustion were achieved. The safety zone before nitrogen injection was analyzed, explosion and combustion zone were eliminated by nitrogen injection and safety production was ensured
