摘要
云台荒煤田的煤系地层——二叠系梁山组、龙潭组以陆源含煤碎屑岩沉积为主,浅—中等覆水,弱还原—弱氧化环境下的潮坪—泥炭沼泽亚相为主要成煤环境和聚煤区,影响煤层厚度变化较大的原因主要有沉积环境、构造和古气候等因素。
Continental margin containing coal clastic sedimentary rocks shallow-medium water covered are dominant in the Permian Liangshan formation and Longtan formation.Tidal flat-peat swamp subfacies under the condition of weak re-duction and weak oxidation are the main coal forming environment and coal accumulation areas.The main reasons for the change of the thickness of coal seam are sedimentary environment,tectonic and paleo climate and so on.
