Abstract: This paper described engineering situation of fire preventing and extinguishing methods in fully mechanized coal
mining face with large mining height in Jinhuagong Coal mine, proposed project design of nitrogen injection for fire prevention,
namely, spontaneous combustion problems in worked out section was solved by using underground transportable nitrogen injection
system to inject high purity nitrogen to worked out section in coal mining face with large mining height during the working face
mining, analyzed nitrogen injection fire-fighting technology along with the mining in embedded pipe in working face, and nitrogen
injection and preventing and extinguishing fire process in worked out section after stopping mining. The results showed that safety
technical measures can ensure the safety of the working face production requirements.

Key words: gas control; underground transportable nitrogen injection system; mining along with injection
