一、不同还原性腐植煤的基本特征在研究华北聚煤区东部晚古生代太原组(C_3)和山西组(P_1~1)煤性质差别及显微特征的基础上,作者认为除煤岩成分和变质程度外,还存在着影响煤质的第三个成因因素——还原性质。不同还原性质的腐植煤,在煤岩、化学等一系列煤质指标上有明显差别,与弱还原性煤相比,强还原性煤具有如下特征:
First, the basic characteristics of different reduction of humic coal In the study of coal accumulation in the eastern part of the northern Paleozoic Taiyuan Formation (C_3) and Shanxi Group (P_1 ~ 1) on the basis of differences in the nature and characteristics of the coal, the authors believe that in addition to the composition of coal and rock In addition to the degree of metamorphism, there is also a third causative factor affecting the quality of coal - the nature of reduction. Different reduction of humic coal, a series of coal and rock chemistry, there are significant differences in coal quality indicators, compared with weakly reducing coal, strongly reducing coal has the following characteristics:
