“灰成分端元分析法”是以SiO2 -Al2 O3 、CaO -MgO及Fe2 O3 -SO3 分别作为三角图端元进行聚煤环境分析的一种新方法。其原理是 :灰成分与煤中矿物质种类与含量具有成因上的相关关系 - -据SiO -Al2 O3 端元特征 ,可以判断介质的总体运动方向 ;由CaO -MgO端元特征 ,可以判断泥炭沼泽受海水影响的程度 ;由Fe2 O3 -SO3 端元特征 ,可以判断聚煤环境的氧化还原条件。该方法用于研究河东煤田 10 # 煤的聚煤环境 ,收到了良好效果 ,证明其不失为传统聚煤环境分析方法的一个有益补充。
“Endmember Analysis of Gray Compositions” is a new method to analyze the environment of coal accumulation by using SiO2-Al2O3, CaO-MgO and Fe2O3-SO3 as trigonometric graphs respectively. The principle is: ash composition and the type and content of minerals in minerals have a genetic relationship - - According to the characteristics of SiO-Al2 O3 end of the media can determine the general direction of movement; CaO-MgO end of the feature can be judged peat The extent of marsh affected by the seawater can be judged by the characteristics of Fe2 O3 -SO3 end-units. The method was used to study the coal accumulation environment of No. 10 coal in Hedong coalfield and received good results. It proves that it is a beneficial supplement to the traditional coal analysis environment.
