| 摘 要： | 通过对平朔9#煤煤样程序升温氧化实验,得出了煤升温氧化过程中H2、CO、CO2、CH4、C2H4、C2H6和C3H8等气体浓度随温度变化的规律,以及指标气体的相关性结果,结果表明:H2与CO具有较强的相关性,可作用为指标气体预测煤层自燃。

| Abstract: | Temperature rising and oxidation experiments on 9# coal samples taken from Pingshuo coal mine area produce the pattern of gas concentration related with the changing temperatures and the relevancies among the index gases such as H2,CO,CO2,CH4,C2H4,C2H6 and C3H8,etc.It is also indicated by the experiments that the relevancies between H2 and CO are strong.They can thus be used as index gases in coal seam spontaneous combustion. |
