Abstract: 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.
