摘要
本文探讨了煤氧化过程中烯烃气体产出特征，分析了烯烃气体产出速率的煤岩学因素，认为煤阶（变质程度）、煤岩成分及还原性等煤岩特征对烯烃气体产出特征有很大影响，乙烯是预测煤炭自燃的较好指标。
The charactcrstic of alkene's generation during coal oxidation and analysis of coal-petrological factors in the rate of alkene's generation are dealed with in the report.The ana-lysis of some coal-petrological factors such as rank (maturity)、maceral(coal composition) and reducibility can not be neglected. The ethylene concentration (density) in air is a better index to predict and forecast spontaneous combustion of coal in mining.
