| Abstract: | IN the light of that the omen of spontaneous fire appears on 73803 working face of Du’erping Coal Mine and the spontaneous fire has further developing and enlarging trend, this paper puts forward the measure for fire extinguishing with nitrogen injection in worked out section, and makes practical application on 73803 working face. The results show that after adopting the measure for fire extinguishing with nitrogen injection, the concentration of CO in each point is obviously reduced, and the fire prevention effect is remarkable. |
