影响混洗煤实际组成准确测定的因素分析

Analysis of influencing factors on accurate determination of actual composition of washed coal

阐述了利用镜质组反射率测定区分不同变质程度的煤混洗时,由于不同产地、不同煤种中所含镜质组的比例不尽相同,镜质组反射率分布图中反映的各单种煤的理论含量不一定符合真实的比例,即进行混洗煤质量分析时,应结合各种分析手段对其进行综合评价。

It is expounded that theoretical content of single coal in reflectogram of vitirnite does not always conform to its real proportion,because there is different vitirnite proportion in different coals or in different places.When different metamorphic grade washed coals are distinguished and determined by means of the reflectance of vitirnite of coal,that is to say,when washed coal quality is analyzed,the comprehensive assessment should be developed combined with all sorts of ways.
