研究煤自然发火过程中指标气体的产生规律.通过对上、下煤样在程序升温条件下测试研究煤层自然发火指标气体的变化规律,确定了测试煤样由低温氧化阶段到快速氧化阶段的临界温度和煤层自燃发火预测预报指标气体.研究结果表明:C2H4和 C2H4/C2H6初始出现时的临界温度、C3H8/C2H4比值峰值点温度与煤样由低温氧化到快速氧化阶段的临界温度具有很强的一致性,均揭示了此时煤样已进入快速氧化阶段.该研究成果对开展煤自燃低温阶段实验研究提供了重要的科学价值.

@@@@In order to investigate the indicator gases in coal spontaneous combustion process, this study tested the changes of spontaneous combustion index with the upper and lower coals in the temperature program. Also, the study had determined the critical temperature and the forecast indicators of coal spontaneous combustion gases from the low-temperature oxidation of coal sample testing phase to the rapid oxidation phase. The study results show that the critical temperature at the C2H4 and C2H4/C2H6 initial occurrence, the temperature at C3H8/C2H4 peak point, and the critical temperature from low-temperature oxidation phase to rapid oxidation phase are strongly consistent. It reveals that the coal sample has entered into a rapid oxidation stage. The study conclusion has an important scientific value for study on low temperature coal combustion.
