    摘要:

    涟邵煤田位于湘中地区,大地构造位置属于加里东褶皱带西北缘。涟邵煤田主体属推覆、滑脱构造类型,沉积盖层构造变形强烈,煤系地层赋存与控煤构造样式关系紧密。本文根据煤系赋存特征、含煤沉积特征、断裂构造展布特点,以区域性大断裂为界,将涟邵煤田划分为三个含煤区,并根据各含煤区的几何形态和形成机制,将涟邵煤田控煤构造样式划分为三大类型、八大亚类。

    Abstract:

    Lianshao coalfield,which tectonically belongs to the northwestern margin of the Caledonian fold belt,is located in the central of HunanProvince.This era mainly has both thrusting nappe structure and gravitation gliding tectonics,and sedimentary cover has strongly tectonic deformation.There exists a close relationship between coal measures occurrence and coal controlling structure styles.Lianshao coalfield is divided into three coal-bearing areas,according to the characteristics of coal measures occurrence、coal-bearing deposit and fault structure.Based on the geometrical morphology and formation mechanism of the coal-bearing areas,the authors put forward a scheme of division for the coal-control structural pattern,which can be divided into three major types,eight subtypes.
