摘要
从聚煤环境特征研究着手,总结出本区龙潭组是在总体海侵条件下形成的陆相至过渡相—河控三角洲沉积,其可采煤层1煤和3煤均发育在废弃的三角洲朵叶上,可采煤层的厚度与其底板砂岩的厚度及环境类型关系密切。在砂岩厚度中等地带,煤层发育较好。研究成果对本区龙潭煤系的资源勘探及开采具有相当重要的指导意义。
Set about coal accumulation characteristics in the area, summed up the Longtan Formation is a limnic to transitional facies - river-dominated deltaic deposit formed under transgressive condition. Mineable Nosl and 3 coal seams were all developed on abandoned delta lobes, coal and coal floor sandstone thicknesses have close relation with environmental types. In sandstone medium thickness zone, developed better coal seams. The result has guiding importance on resources exploration and exploitation.
