Based on the study of three zones division and distribution law of Shuiyu Mine 61106 working face, parameters of inerting bandwidth, length oxygen content of initial and intermittent nitrogen injection of nitrogen injection fire-fighting technology in oxidizing zone were settled. Auxiliary spraying of chemical inhibitor and strengthening of air distribution, monitoring and recovery rate in working face were improved to avoid probability of a natural fire to the maximum.
