【摘要】 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 ,分析了淮北煤田二叠系的沉积特征、沉积序列和沉积环境及其演化 ,鉴别了沉积相 ,初步进行了聚煤规律分析。研究表明 ,淮北煤田二叠系广泛发育三角洲沉积体系 ,而且三角洲沉积体系的废弃阶段是聚煤作用的最佳时期 ,三角洲平原是聚煤的最佳场所。更多还原

【Abstract】 By the means of the principle and the method of the sedimentology and coal geology, and based on the detailed coring data analysis, this paper focused on the sedimentary environment, sedimentary character, sedimentary sequence, and the regularities of Permian age coal accumulation in Huaibei coalfield. The study shows that the delta depositional system is well developed in the study area, and the abandoned stage of the delta sedimentary system is the best time for coal accumulation, and the delta plain is the best place for coal accumulation.更多还原
