讨论了露天矿褐煤自然发火内在因素的３个基本问题：褐煤低温氧化反应、褐煤自然发火临界温度及褐煤的吸氧量。为露天煤矿自然发火防治提供了基础理论依据。
Three basic problems of internal combustion of lignite spontaneous combustion are discussed: low temperature oxidation of lignite, critical temperature of lignite spontaneous combustion and oxygen absorption of lignite. It provides the basic theory basis for the prevention and control of spontaneous combustion in surface coal mines.
