摘要
煤的变质程度、分子结构、煤岩成分不同,自燃倾向有很大差异.煤氧化自热温升大体分3个阶段,每个阶段都有相应的气体产物发生.由检测到某种气体产物,可推断煤氧化自热温度范围,提前预报煤自燃状况,及时采取措施,防止煤自然发火.
Different degree of coal metamorphism, molecular structure and petrographical compositions bring about great difference in proneness of spontaneous combustion. The temperature rise due to oxidation of coals generally can be divided into three stages, and corresponding gases are produced in each stage. The range of temperature of spontaneous combustion can be predicted by measuring the gases produced. And state of spontaneous combustion can be forecast. Measures can be taken to prevent spontaneous combustion of coals.
