| 摘 要： | 通过对重庆市沥鼻峡背斜盐计矿区含煤地层研究，探讨了矿区龙潭组的沉积特征和聚煤规律，得出矿区龙潭组为泻湖-海湾-潮坪沉积体系，成煤时期的不同沉积环境，聚煤沉降幅度小，沉积速度和物质补偿均衡，有利于泥炭堆积，因此矿区含煤层数、煤层厚度较稳定，该区处于华蓥山潮坪地带，是龙潭期聚煤中心之一。

| Abstract: | Analyzed Yanjing mining area coal-bearing strata, Libixia anticline, Chongqing City, discussed mining area Longtan Formation depositional features and coal-accumulating pattern, considered that the Longtan Formation belongs to a lagoon-bay-tidal fiat depositional system. Different depositional environments, lesser settling scope, balanced settling velocity and material compensation during coal-forming stage were favorable to peat accumulation. Thus the coal seam number and thickness are stable in the mining area. The area is situated at Huayingshan tidal fiat zone is one of coal-accumulating center during Longtan stage. |
