摘　　要：高瓦斯近距离煤层群自然发火防治问题一直是煤矿火灾防治方面的一项难题。工作面自然发火一般采取单一的灭火方式。针对煤矿自然发火,提出联合注氮的理念进行灭火,分析了氮气与液氮的灭火机理,并在黄白茨煤矿021005工作面进行了实施。对工作面注液氮、注氮气进行防灭火,随后获得的气体监测数据证明,防火效果较为理想,为高瓦斯煤矿近距离煤层群防灭火治理方面积累了宝贵经验。Gas close distance coal seam group of spontaneous combustion prevention and control of coal mine fire prevention and control is the key aspect of a problem.In view of the working face general adopt the mode of single fire extinguishing spontaneous combustion.For coal spontaneous combustion,this paper put forward the concept of a combination of nitrogen injection for fire extinguishing,nitrogen and liquid nitrogen fire extinguishing mechanism were analyzed,and the methods of nitrogen and liquid nitrogen fire extinguishing were put into practice.The gas monitoring data has proved that the ideal results have been achieved,and has accumulated valuable experience for fire control of coal mine with close-distance coal seams.
