为更好了解低变质程度煤样一次自燃和二次复燃过程中的变化,通过真密度测试实验、油浴程序升温实验和德国布鲁克VERTEX 70傅里叶变换红外光谱仪,从微观、宏观角度阐述了2次氧化造成指标变化的本质原因。该实验研究为低变质煤的开采及防灭火工作提供有力的理论依据。
In order to understand the changes of low-grade coal spontaneous combustion and secondary re-ignition process better, the experiments of true density test, oil bath temperature-programmed experiment and German Bruker VERTEX 70 Fourier transform infrared spectrometer The oxidation of the two indicators of the nature of the causes. The experimental study provides a powerful theoretical basis for the mining of low-metamorphic coal and fire prevention work.
