| 摘 要： | 煤的热谱(DTA、DSC、TG)特征与煤的其他物化特征参数一样,是煤大分子结构特征的反映,可作为研究煤化作用的参考和无烟煤分类的辅助标志。本文介绍了湖南省不同变质程度煤的热谱特征和试验所发现的热谱曲线、峰温与煤及瓦斯突出强度、无烟煤三小类的关系,并试验证明利用热分析曲线进行煤层对比的可能性。

| Abstract: | The thermal spectra (DSC, DTA, TG)of coal, like other physical and chemical parameters of coal, can reflect the macromolecular structure of coal, which can be used as parameters for studying coalification and as supplementary indicators for the classification of anthracite. This paper describes the thermal spectra of different-metamorphic-grade coal in Hunan province, and experiment-detected relationship between thermal spectrum curves, peak temperature and gas inrush as well as the three lithotypes of anthracite, with an attempt to prove the possibility of using thermal analysis curves to make correlation of coalseams. |
