摘要
In order to discuss the influence of coal-forming environmental conditions on coal properties, the authors study the characteristics and its control factors of major elements in coal ash of different coal accumulating systems. Ash production, mineral and organic carbon content of coal samples from different coal accumulating systems of Zhiluo and Yan’an Formations show obvious change trend. Based on synthetic analysis, the authors hold that the diversities of ash production, mineral content and organic carbon content of coal seamⅡ, Ⅲ, Ⅳof Yan’an Formation, coal seamⅤof Yan’an Formation and Zhiluo Formation, are mainly controlled by coal-forming environmental conditions. The degree of influence on coal by detrital material during coal forming process affects mineral content, ash production and organic carbon content of coals.
