摘　　要：为了查明霍西煤田灵石县安益矿区主采煤层1#煤的煤岩学特征,采用显微光学、工业分析等方法,探讨了1#煤分层样品的显微煤岩及煤质特征。结果表明:1#煤沉积环境以上三角洲相为主,宏观煤岩类型主要分别为半亮型及光亮型煤,显微煤岩组分均以镜质体为主,原始泥炭沼泽沉积环境为深积水缺氧的沼泽成煤环境,相图显示其为潮湿森林沼泽环境;1#煤为中等煤化程度,可用作炼焦配煤和动力用煤。The dissertation have based on No1 main mineable coal in Lingshi Anyi mining area of Huoxi coalfield as research objects, and samples were analyzed by optical microscopy, the method ofphase diagram. The results have showed the sedimentary environment of No. 1 coal was mainly the front delta facies, respectively the semibright coal and the bright coal, vitrinite is the main ingredients, and the coals were formed in deep-water swamp with oxygen-deficit coal-forming environment; the primitive coal-bearing environment of No.1 coal seam was the wet forest swamps according to the diagram; No.1 coal are in the medium degree of coalification, which could be used for blending coking coal and power coal.
