摘　　要：根据钻孔岩芯及煤质测试结果,应用沉积学、岩石学、煤田地质学等理论对研究区沉积背景、含煤地层进行了分析,在此基础上对含煤地层龙潭组沉积相进行了划分和研究,揭示了沉积环境、沉积相特征及空间展布。研究区龙潭组沉积相类型有潟湖-潮坪、三角洲及障壁岛-潟湖-潮坪相。最后,依据研究区的古气候、古构造及沉积环境对聚煤作用的控制因素等方面,总结了聚煤规律,为研究区煤炭资源勘探与开发指出了方向。By drilling cores and coal quality test results,the sedimentary background and coal-bearing strata in the study area are analyzed with the theories of sedimentology,petrology and coalfield geology.Sedimentary facies of Longtan formation is divided and studied on this basis. The characteristics of sedimentary environment and facies are revealed. The types of sedimentary facies are lagoonal-tidal flat facies,delta facies and barrier island-lagoonal-tidal flat facies in the study area. Finally,summarized the coal-accumulation regularity from the control factors of coal accumulating effect of geologic,paleostructure and sedimentary environment,and so on. It points out the direction for the exploration and development of coal resources in the study area.
