毛易矿区位于湖南长邵断坳北段，属于涟源坳陷中部隔挡式褶皱带，区内逆冲推覆构造较为发育。通过野外观测及资料整理，分析了研究区构造几何形态，得出矿区及其外围构造具有明显分带分段特征的结论：以向斜为主体，向斜两翼发育逆冲推覆构造，自北向南可分为北段、中段、南段；根据褶皱展布特征，自西向东可分为西带，中带和东带。研究认为，西带构造变形强于东带，研究区构造演化为共轭逆冲断层模式，受后期构造影响，煤系不均匀分布于西带和东带，其中北段东带与南段东带逆冲构造下伏地层是有利的找煤区域。

The Maoyi mine area is situated in the north sector of Changsha-Shaoyang faulted depression in the middle Lianyuan depres-sion ejective folded zone;thrust nappe structure is rather developed in the area. Based on field observations and data processing, ana-lyzed structural geometric patterns have concluded that the mine area and periphery structures have zoning and sectoring characteris-tics. With the syncline as the principal part, thrust nappe structures are developed on the two limbs, from north to south can be subdi-vided into north, middle and south sectors;based on fold extending characteristics, from west to east can be subdivided into west, mid-dle and east zones. The study considered that the deformation of west zone is stronger than east zone;structural evolution in study area belongs to conjugated thrust mode. Impacted by succeeding structures, coal measures is heterogeneously distributed in west and east zones, in which, nappe structure underlying strata in north sector and south sector of east zone are favorable coal prospecting areas.
