Mylonitic coal may develop in the center of strongly deformational belt in pressing tectonic stress field. Since mylonitic coal is limited in a narrow area, biggish area in that tectonic coals of brittle deformation distribute is favorable for CBM exploration. Moat of areas are advantageous for formation of coalbed fractures and increase of permeability in extension stress field, but it is easy to beget dissipation of CBM and decrease of gas content. Therefore, study of structure of gas reservoir should be taken seriously.
