| 摘 要： | 利用傅立叶变换红外光谱(FTIR)分析技术，对暴露于空气中不同时期的氧化煤样的红外光谱进行了测试与分析。根据煤的主要特征光谱峰，确定出煤中参与氧化的不同种类的特征官能团；通过特征官能团吸收光谱强度变化，得出煤在氧化进程中官能团数量的变化规律，从而确定出煤的氧化能力。应用该技术对孔庄矿煤层的研究结果与现场实际基本相符。

| Abstract: | An Fourier transform infrared spectrum apparatus was used to measure and analyze the infrared spectrogram of coal exposedto atmosphere at different time.According to the characteristic spectrum peaks,the wave numbers of the major functional groups of coal involved in oxidation were made certain.The numbers of functional groups in the process of oxidation,which indicated the ability of oxidation of coal,were acquired by analyzing the absorbance changes of the characteristic functonal groups.The research results of applyingthis thechnology to study low-temperature oxidation of the Kongzhuang coal agree well with the practical conditions. |
