平顶山矿区含煤地层沉积环境及聚煤特征

Features of coal bearing strata sedimentary environment and coal accumulation in Pingdingshan Mining Area

通过对大量钻孔资料分析,运用沉积学、煤田地质学的基本理论和方法,分析了平顶山矿区含煤地层的沉积环境及其演化,并结合区域构造地质背景,进行了聚煤规律研究,结果表明,平顶山矿区含煤地层形成于滨海沉积体系和三角洲沉积体系。

With the analysis on the great borehole information, with the basic theory and method of the sedimentary and coalfield geology, the paper analyzed the sedimentary environment and evolution of the coal bearing strata in Pingdingshan Mining Area. In combination with the regional tectonic geological background, the paper had a study on the coal accumulation law. The results showed that the coal bearing strata in Pingdingshan Mining Area was formed in a littoral sedimentary system and delta sedimentary system.
