通过实地探测皖南地区煤层剖面及进行的粒度分析,并综合利用煤沉积学及地质学相关知识,结合皖南地区各煤田的沉积环境、沉积基底、成煤条件、地质构造和聚煤特征,分析了地面水赋存条件下皖南地区龙潭组的沉积环境及演化规律,同时,对地下煤层聚集的特征进行了分析。 Through the field exploration of the coal seam profile in Anhui Province and the particle size analysis, and comprehensively using the knowledge of coal sedimentology and geology, combined with the sedimentary environment, sedimentary basement, coal-forming conditions, geological structure and coal-accumulating characteristics of coal fields in southern Anhui Province, The depositional environment and evolution of Longtan Formation in the southern part of Anhui Province under the condition of surface water storage. Meanwhile, the characteristics of underground coal seams are analyzed.
