浅谈滇东恩洪矿区沉煤环境及聚煤规律

恩洪矿区处于滇东晚二叠世聚煤区中部偏南的海陆过渡地带,总体上属上三角洲平原沉积环境,沉积构造地貌单元属玄武岩斜坡区与浅陆表海区过渡带。从沉积环境、沉积相、煤层迁移规律及聚煤控制因素等方面,阐述了滇东恩洪矿区沉煤环境及聚煤规律。

Talking about the Coal-depositing Environment and Coal- accumulating Law in Enhong Mining Area in the East of Yunnan Province

Enhong Mining Area is in the south-central sea-land transition zone and in Late Permian coal-accumulating region in the east of Yunnan Province,and generally speaking,it is delta plain depositional environment,whose depositional structure＇s geomorphic unit is transition belt from basalt slope area to shallow epicontinental sea area.This paper expounds the coal-depositing environment and coal-accumulating law of Enhong Mining Area in the east of Yunnan Province from coal-depositing environment,sedimentary facies,coal seam migration rule,and coal-accumulating control factors,etc.
