面对煤自燃火灾依然严峻的形势,探究如何阻止自燃的蔓延无疑是现代化矿井建设的重要课题。尽管防灭火技术取得了一定的发展,但其效果尚未突出。加强对防灭火材料的基础研究,有利于开发新技术,推动防灭火技术的成熟。本文综述了阻化剂、惰性气体、泡沫、胶体材料的研究情况;分析了各种防灭火材料的灭火机理;并介绍了各种防灭火材料灭火的优缺点,提出了一些防灭火技术在实际应用中所面临的技术难题。最后,对各种防灭火材料进行了一定的总结。 In the face of the situation that coal spontaneous combustion is still harsh, exploring how to prevent the spread of spontaneous combustion is undoubtedly an important issue in modern mine construction. Although fire prevention technology has made some progress, but its effect has not yet prominence. Strengthen the basic research on fire-prevention materials is conducive to the development of new technologies to promote the maturity of fire-fighting technology. In this paper, the research situation of retarding agents, inert gases, foams and colloidal materials are reviewed. The fire extinguishing mechanism of various fire extinguishing materials is analyzed. The advantages and disadvantages of fire extinguishing materials are introduced. Some fire extinguishing technologies are put forward in practice Application of the technical problems faced. Finally, a variety of fire-extinguishing materials were summarized.
