摘　　要：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．This paper deals with the possibility of ductile shear zone formed in coal bed based on the moleculry structure of coal and softening chareteristic of coal under low tempereture condition, and the change of water and gas in coal, as well as the stress condition of the ductile shear deformation occurred in the coal bed. There is the characteristic of ductile in the coal seam. The physical and chemical copability of the coal is the basis that makes ductile deformation occur easily. Corresponding ground temperature field, beding ductile shear force and tectono_thermal events are overlapped together to become the outside conditions of making the coal occur ductile shear deformation. Beding ductile shear zone and its tectonic community occured in coal seam lies at shallow (earth′s) crust with its own characteristics of manifestation.
