| 摘 要： | 利用自行设计的煤炭自燃热解实验装置，研究了不同供氧浓度下煤样升温氧化特性及自燃升温过程中产生氧化气体和碳氢类气体解吸涌出规律，并在此基础上确定了梁宝寺煤矿煤炭自燃预报的指标气体。实验结果表明：若研风流中检洲到C2H4气体，此时煤温可能达到或超过100℃左右，需采取有效的措施，进行灭火。

| Abstract: | The temperature rise and oxidation features of coal samples with the different concentrations of oxygen supply as well as the desorption rule of the oxidation gases and hydrocarbon gases produced in the process of self-ignition and temperature rise of coal were studied by using the self-designed pyrolysis apparatus about spontaneous combustion of coal.And based on that,the indicative gases for predicting the coal spontaneous combustion in Liangbaosi Colliery was determined.The experimental results show that... |
