火区启封时煤温是决定复燃的重要因素。为研究起始温度对煤样二次氧化特性的影响，将淮南朱集煤矿原始煤样程序升温至170℃后分别降温至20、40、60、80、100、120℃，再程序升温后测定O2、CO、CO2等气体浓度。采用三阶弱化缓冲分析煤样二次氧化特性。

In the process of unsealing coal fire area, temperature is an important factor for the resurgence .In order to study the characteristics of coal samples′ secondary oxidation of the different initial temperature effects, the original coal samples of huainan zhuji coal mine ware warmed to 170℃by temperature-programmed experiments. Then these samples were cooled to 20, 40, 60, 80, 100 and 120 ℃ to measure the gas concentrations of O2, CO, CO2 and other gases in the process of the secondary oxidation. With the Weakening buffer through third order ,the results of characteristics of the reoxidized coal samples were analyzed.
