通过对区内晚古生代煤层的埋藏史、古地热史和生烃演化史的研究，认为煤层埋藏史类型以及发生于燕山运动中期的第２次生气作用是控制煤层气生成保存条件的重要地质因素，进而指出区内阳城—沁水、沁源—沁县和安泽等地区可能最具有煤层气勘探前景． By studying the burial history, ancient geothermal history and evolution history of hydrocarbon generation in the Late Paleozoic coal seams in the area, it is considered that the types of burial history of coal seams and the second gas-generating effect occurred during the mid-Yanshanian movement are important geologic factors for controlling the formation and preservation of coalbed methane. It is pointed out that Yangcheng-Qinshui, Qinyuan-Qinxian and Anze areas in the area may have the most prospect of CBM prospecting.
