Abstract

Models are developed for spectral classes of GZh and Zh coal concentrates based on diffuse-reflection IR spectra, by independent modeling of class analogs. The spectral classes derived for such coal are shown to be clearly distinct. Individual models of spectral classes for samples of GZh and Zh concentrates from different enrichment facilities are created and compared. On the basis of the spectral classes, which reflect the chemical structure of a limited mass of coal, the coal rank may be established, and concentrates from different enrichment facilities may be compared and contrasted. In addition, rapid quality control is possible.

煤的光谱分类模型

摘要

通过对类别相似物进行独立建模，基于扩散反射红外光谱为GZh和Zh精矿的光谱类别开发了模型。显示出从此类煤中得出的光谱类别明显不同。创建并比较了来自不同浓缩设施的GZh和Zh精矿样品的光谱类别的各个模型。基于反映有限质量的煤的化学结构的光谱类别，可以建立煤等级，并且可以比较和对比来自不同浓缩设施的精矿。另外，可以进行快速的质量控制。
