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。
In order to identify the coal petrology characteristics of the primary coal seam # 1 in the An Yi mining area, Stonehenge County, the micro-coal and industrial analysis methods were used to discuss the micro-coal rock and coal Qualitative characteristics. The results show that: the sedimentary environment of # 1 coal is dominated by the upper delta facies, the macroscopic coal and rock types are mainly semi-bright and bright coal, the microscopic coal and rock components are mainly vitrinite, and the original peat swamp sedimentary environment is deep Hydrothermal anoxic marsh coal environment, the phase diagram shows that it is wet forest swamp environment; 1 # coal for the degree of medium coalification, can be used as coking coal and power coal.
