摘 要: 應(yīng)用突變理論對火災(zāi)災(zāi)變時井下大氣性狀的變化過程進行了研究，建立了災(zāi)變過程大氣性狀的突變模型。 該模型的分析結(jié)果與實際情況一致，利用這一突變模型可確定防治火災(zāi)的各種有效措施，確保礦山安全生產(chǎn)得以順利進行。

Abstract:Using catastrophe theory, the change of mine atmospheric properties during underground mine fire was studied, its catastrophe model was constructed, and the results of this model correspond with the fact. According to the model many efficient measures to prevent and eliminate mine fire can be chosen so that regular mining production may proceed in safety state.
Key words: mine fire atmospheric properties catastrophe analysis
