摘　　要：通过对都格井田含煤地层研究,探讨了井田含煤地层的沉积特征和聚煤规律,井田龙潭组为三角洲与泻湖—潮坪沉积复合体系,其中三角洲发育时期是本区主要的聚煤期,其沉积环境稳定,含煤性较好.煤层层数较多.厚度较稳定。Based on the study of the coal-bearing strata in Duge coal field, the sedimentary characteristics of coal-bearing strata and the coal-accumulating patterns are discussed. The Longtan For- mation is a delta-lagoon-tidal flat sedimentary system, in which the delta development period is the main coal- accumulating, its sedimentary environment is stable, coal-bearing better, more coal layers, the coal thickness is the more stable.

关 键 词：龙潭组 含煤地层 沉积特征 聚煤规律
