毛易矿区及其外围的主要控煤构造样式为隔档式褶皱和层间滑动断层，在经历了印支期以来多期构造作用后，形成了以毛易-晏家铺向斜为主体，逆冲推覆构造为基本构造格架，且盖层构造具有较明显的南北分段、东西分带的特征。研究区大量斜歪褶皱、构造透镜体、擦痕等构造均指示逆冲推覆的性质，镜下显微构造现象显示了该区所处的浅层低温变形环境。软弱层的存在为滑脱构造提供了基础，煤田构造演化可划分为3个阶段。

The main coalGcontrolling structure modes in Maoyi mining area and its periphery are ej ective folds and interlayer gliding faults? This area has been suffered multiGstage tectonic transform since Indosinian,and formed the tectonic characteristics that the MaoyiGYanjiapu synG cline acts as the main body,thrust nappe structure as the basic structural frame,and meanwhile, the cap rock structure has the obvious feature of “northGsouth segmentation and eastGwest zonaG tion”?Multiple inclined folds,tectonic lens and scrapes all indicate the thrustGnappe property and microstructure phenomena represents this area locates in the deformed environment with shallow layer and low temperature?The existence of the soft layer provides a basis for detachment strucG ture?And the evolution of coalfield structure can be divided into three stages.
