摘要
通过对准东煤田五彩湾矿区下侏罗统八道湾组开展沉积学、层序地层学研究,分析在层序地层格架下可采煤层的分布特征和煤层聚集的主要控制因素,总结聚煤规律.八道湾组煤层主要发育于两期湖扩体系域沉积期的滨浅湖相区域,区内湖扩体系域滨浅湖相向区外西、南、东侧仍有较大的展布区域,具进一步找煤潜力.
Abstract
Sedimentology and sequence stratigraphy of badaowan Formation in Wucaiwan mining area of Zhundong coalfield,are analyzed by using the methods of coal geology and sequence stratigraphy,and the distribution characteris-tics of coalbed under the sequence stratigraphy framework are discussed,the main controlling factors of coalbed accumu-lation are analyzed,and the law of coalbed accumulation is preliminarily summarized.The results show that the coal seams of badaowan Formation are mainly developed in the coastal and shallow lake area during the sedimentary period of the two-stage lake expansion system tract,and the coastal and shallow lake in the inner lake expansion system tract still spread to the west,south and east of the area.Therefore,there is a potential for further coal exploration in the west,south and east of the area.
