摘　　要：为了深层次解析煤岩组成对原料煤加工利用过程的影响,选取煤岩亚组分作为考察因素并研究其基础特性,基于煤岩亚组分真相对密度、挥发分、元素组成等指标的加权特性,采用试验分析与数学计算相结合的方法研究了代表性焦煤均质镜质体、基质镜质体、丝质体、粗粒体等煤岩亚组分基本工艺性质。结果表明,同等变质程度下,丝质体和粗粒体的真相对密度较大,半镜质组次之,均质镜质体和基质镜质体的真相对密度较小;不同煤岩亚组分挥发分由大到小依次为:均质镜质体>基质镜质体>半镜质组>丝质体>粗粒体;碳元素含量及芳碳率关系为:均质镜质体<基质镜质体<半镜质组<丝质体、粗粒体,氢氧元素含量、H/C原子比及O/C原子比与此相反。In order to investigate the influence of coal lithotypes on coal utilization,the submaceral was selected as investigation factor,its basic characteristics were investigated.Based on submaceral’s weighting characteristic of true relative density,volatile matter and elementary composition,the basic characteristics of typical coking coal were analyzed by experimental analysis and mathematical calculation.The results showed that under the same metamorphic grade F and Ma had larger true relative density,then SV,C1 and C2 had relative smaller true relative density.Volatile matter of different submacerals from big to small was C1,C2,SV,F,Ma.Carbon element content and aromatic-carbon ratio from small to big was C1,C2,SV,F,Ma.Hydrogen content,oxygen content,H/C and O/C were different from carbon element content.
