【摘要】 论述了活化能的概念及确定方法，利用活化能指标来划分煤的自燃倾向性，不仅分类简单统一，而且能从物理化学本质上来揭示自燃倾向．论述了煤的活化能与自然发火期的关系，通过活化能将火区渗流、弥散及热传导过程统一起来，为建立整体统一的自然发火数学模型奠定了基础．更多还原

【Abstract】 The concept and determine method of activation energy are discussed, spontaneous combustion tendency of coal is divided by using activation energy index, the method of classification is not only simple and unified, but the spontaneous combustion can be opened out from its physical and chemical nature.The relations between activation energy and spontaneous combustion are discussed, activation energy equation and seepage flow and dispersion of freearea and thermal transmittance are united,foundation is settled for the establish of integral and unified mathematics model of spontaneous combustion.更多还原
