根据煤的分子结构和煤的低温软化特征，煤中水、气条件以及产生韧性剪切变形的应力条件，初步论述了煤层中形成顺层韧性剪切带的可能性．煤层具有韧性特征，煤本身的物理化学性能是其容易发生韧性变形的基础，相应的地温场和顺层剪切力以及构造热事件叠加在一起是煤发生韧性剪切变形的外部条件．煤层中形成的顺层剪切带及其构造群落位于地壳浅层，表现形式上有其独有的特征． According to the molecular structure of coal, softening characteristics of coal at low temperature, water and gas conditions in coal and the stress conditions of ductile shear deformation, the possibility of formation of bedding ductile shear zone in coal seam is discussed. The coal seam has the characteristics of toughness. The physical and chemical properties of the coal itself are the basis for its easy occurrence of ductile deformation. The corresponding geothermal field, bedding shear and tectonic thermal events are the external conditions for ductile shear deformation of coal. The formation shear strata and their tectonic communities formed in the coal seam are located in the shallow crust and have their own unique characteristics.
