摘要
在分析徐州矿区20个工作面标志性气体实验数据的基础上,重点研究CO、C_2H_4、C_2H_6气体在煤氧化自燃过程中的变化规律,提出了煤自燃标志性气体与煤温间的定量关系和早期预测预报煤自然发火的指标。
On the basis of analyzing experimental data of marking gas in 20 working faces in Xuzhou mining areas, the changing rules of CO、 C2H4, C2H6 gases during oxidation and spontaneous combustion of coal were studied in detail. The quantitative relation between marking gas of coal spontaneous combustion and coal temperature and early stage prediction index of coal spontaneous combustion were raised.
