摘　　要：为了掌握孙疃煤矿10煤最短自然发火期,通过对煤自然发火期确定方法的比较分析,确定实验条件下最短自然发火期的计算模型;对孙疃煤矿10煤层煤样在不同温度段的吸氧速度、失水量、解析瓦斯含量进行测定,进而分段计算了达到临界温度需要的时间,确定该煤层的最短自然发火期,为制定防灭火措施提供依据。In order to grasp the shortest spontaneous combustion period of the tenth coal seam m Suntuan Coal Mine, by the comparative analysis on the determination methods of coal spontaneous combustion period, the calculation model of the shortest spontaneous combustion period is determined. According to the tenth coal samples of Suntuan Coal Mine, the velocity of consuming oxygen, water loss rate, and gas contentat different temperature sections are determind.The time to reach a critical temperature needed is calculated in subparagraph. The shortest spontaneous combustion period of the tenth coal seam is determined, a basis is provided for the formulation of the fire prevention and extinguishing measures.
