| Abstract: | The paper introduces the use of coal petrology method to study micro-fractures of high rank coals of the Carboniferous period coal produced in the northern foreland basin of Dabie Mountain, and to explore the distribution characteristics of micro-fracture in different deformational-metamorphic types coals and the influence factors. The particularity of the geological background results in several scales of structural fracture, especially the complexity and particularity of micro-fracture distribution and evolution, as influenced by the multi-stage tectonic deformations and magmatic activities. |
