Deformed coal in formation process will be affected by different tectonic action, these tectonic action to make coal deformation, these deformation includes not only the macro deformation also include micro deformation. Previous people have more research on macro deformation to the influence of methane adsorption and less research on micro deformation to the influence of methane adsorption, So this paper research from micro deformation of the coal, Analyses the microstructure of coal tectonism the effects o...
