湘中梅城寒婆坳区控煤构造样式研究

Study of Coal Control Structural Pattern in Xiangzhong Meicheng-Hanpoao Area

梅城-寒婆坳区位于涟源凹陷西部叠瓦逆冲带,区内沉积盖层变形强烈,构造复杂,基于煤炭资源调查评价工作成果,对区内测水煤系展布特征、赋存特征等进行分析,根据含煤区的剖面形态、应力机制、形成机理,将梅城-寒婆坳区构造控煤样式划分为2类4型,为今后开展煤炭资源的勘查与评价有重要意义。

Meicheng-Hanpoao area is located in the western imbricated thrust belt of Lianyuan basin.It has strong deformations of sedimentary cover with complex geological struture.Based on the results of coal resource investigation and evaluation,this research analyzes the character of the distribution and occurrence of water-coal measures in the region.According to the profile shape,stress mechanism and formationmechanismof coal-bearingarea,thisresearchdividesMeicheng-Hanpoao areainto"2-category,4-types"in the structural coal control pattern.It has a great significane of coal resources exploration and evaluation in the furture.
