摘　　要：采空区煤自燃容易造成资源的浪费和环境的污染,同时能够引发瓦斯燃烧、粉尘爆炸等重大灾害性事故,进而造成财产损失和人员伤亡。为进一步提升煤自燃“防-抑-灭”协同防灭火技术,推动我国煤炭资源的绿色开采,对采空区煤自燃的原因及影响因素进行了分析;全面阐述了现有的采空区火灾的预防、抑制与灭火技术,并对比分析了各类“防-抑-灭火”技术的优缺点,指出了治理采空区煤自燃过程中存在的问题。The spontaneous combustion of coal in the goaf can easily lead to waste of resources and environmental pollution, and at the same time, it can cause major catastrophic accidents such as gas combustion and dust explosion, resulting in property losses and casualties. In order to further improve the coal spontaneous combustion “preventing-suppressing-extinguishing”coordinated fire-fighting technology and promote the green mining of coal resources in our country, the reasons and influencing factors of coal spontaneous combustion in goaf were analyzed, this paper summarizes the existing fire prevention, suppression and fire extinguishing technologies in goaf, comparatively analyzes the advantages and disadvantages of various types of “preventing-suppressing-extinguishing”technologies, and solves the problems existing in the process of coal spontaneous combustion in the goaf.
