摘　　要：利用绝热低温自热氧化试验方法,研究了褐煤在完全干燥和潮湿与烟煤低温氧化过程,得到了褐煤和烟煤自加热温升曲线和温升速率,同时分析了水分对煤炭低温自热氧化影响。研究了利用绝热试验方法判断煤的自燃倾向性可行性。An adiabatic testing procedure for studying the process of the low-temperature oxidation of the lignite and the bituminous coal was used, under completely dry and moist condition. The curve and the rate of temperature rise against time on the self-heating of the lignite and the bituminous coal are obtained by the method, and effect of the moisture content for the low-temperature oxidation of the coal was analyzed at the sametime. And the feasibility of determining the propensity of coal to spontaneous combustion by using adiabatic testing procedure was also studied
