摘　　要：从马儿庄勘查区含煤地层的沉积特征和岩石学特征入手,对勘查区含煤地层的沉积演化和聚煤规律进行了详细的研究。研究表明:沉积环境主要以河流三角洲相为主,聚煤规律具有明显的周期性变化的特点,存在着各种不同的沉积相组合和沉积单元。Beginning from the sedimentary characteristics and coal accumulation of coal-bearing strata in Maerzhuang exploration area, systematic research the sedimentary evolution and coal accumulation of the coal-bearing strata. The results show that the fluvial delta is the main sedimentary environment and coal accumulating law has obvious characteristics of cyclical changes,there are variety of different combinations of sedimentary facies and sedimentary units.
