研究了构造演化特征及对煤层气的控制作用。结果表明，印支运动以来，构造演化对煤储层物性具有明显的控制作用。受北方近东西向断裂的制约，北部地区煤层气勘探前景不佳。而在南区东部，煤的分布受褶皱样式的控制。苏仙向斜南部和南坪向斜的煤层埋深、煤体结构、含气性、含气量和渗透率等因素对煤层气的运移、富集和保存都是有利的。因此，具有良好的煤层气勘探前景。临涣矿区大变形构造煤广泛发育，煤体结构复杂，勘探前景较差。涡阳矿区煤层气储量相对较少。但由于其良好的渗透性，值得进一步研究。
Characteristics of structural evolution and coalbed methane controlling were researched. The results indicate that since the Indo China Movement, the physical characteristics of coal reservoir has been controlled by structural evolution obviously. Bordered by the northern Suxian fault trended EW, the exploration prospect of coalbed methane in the north area is not good. While in the eastern part of the southern area, distribution of coal is controlled by the pattern of folds. In southern Suxian syncline and Nanping syncline, buried depth of coal seams, coal structure, gas bearing character, gas content and permeability are all favorable for the migration, concentration, and preservation of coalbed methane. Therefore, they have a good exploration prospect of coalbed methane. Because the greatly deformed tectonic coal develops widely and the coal structure is complex, Linhuan mining area has a bad exploration prospect. In Guoyang mining area, the amount of coalbed methane is relatively small. However, it is worth to have a further investigation because of the good permeability.
