| 摘 要： | 东胜煤田深部区延安组主要发育2-6五个煤组,含煤26层,煤层总厚度5.9～36.7m,根据33个钻孔293个煤样的煤质分析结果,研究区各煤层有机显微组分均以镜质组为主,含量为51.4%～83.0%,惰质组占17.0%～48.0%,煤中矿物质含量为0.18%～14.5%,以粘土矿物为主。从下到上镜质组含量有所增加,常量元素含量较稳定。本区煤类属不粘煤,工业利用以动力用煤为主,因有害元素总体含量较低,其利用不会对环境产生影响。

| Abstract: | In the deep part of the Dongsheng coalfield is developed mainly Nos.2-6 five coal groups, 26 coal seams with total thickness of 5.9-36.7m. According to coal quality analyzed results of 293 coal samples from 33 boreholes, have found that the organic maceral of each coal seam in the study area is mainly vitrinite, account for 51.4%-83.0%, inertinite 17.0%-48.0%, mineral matter 0.18%-14.5% mainly clay minerals. Vitrinite content has increasing to some extent from bottom to top; content of macroelement is rather stable. Coal rank in the area belongs to non-caking coal and mainly used in power generation. Because of low content of harmful elements generally, its utilization will not impact environment. |
