在研究我国含煤岩系古地理类型和剖面沉积相构成特征的基础上,提出含煤岩系古地理类型的半定量分类方案,选取三种主要沉积介质营力作用即海洋作用,河流作用和湖泊作用,作为分类的参数且分别构成扇形半定量分类图的S、R和L三个端元,并通过分析反演构成含煤岩系沉积相的介质营力类型及其相对丰度实现S、R和L三参数对含煤岩系影响程度的定量化分析。
Based on the study of the paleogeographic types and the sedimentary facies in the coal-bearing rocks in China, a semi-quantitative classification scheme of palaeogeomorphic types of coal-bearing rocks is proposed. The three major sedimentary media are the oceanic operations, Lakes, as the parameters of the classification, and form the S, R and L endpoints of the fan-shaped semi-quantitative classification diagram respectively. By analyzing the media type and its relative abundance of the inversion sedimentary facies which constitute the coal-bearing series, Quantitative analysis of influence degree of R and L parameters on coal - bearing rock series.
