摘　　要：运用沉积学、构造地质学、煤地质学、数学分析等相关学科和方法,综合分析瓦斯涌出量的地质构造、顶底板岩性、上覆基岩厚度等地质因素,对阳城地区瓦斯含量、涌出量进行量化预测,并作出其全井田瓦斯含量、涌出量的等值线图。研究表明,阳城井田属低瓦斯矿井,瓦斯含量的变化主要与煤层埋深有关,随着煤层上覆基岩厚度以及煤层埋深的增高,瓦斯含量与涌出量在区内由北向南有增高趋势。By using sedimentology,structural geology,coal geology and mathematics methods,geological factors which will influence gas emission,such as geological structures,roof and floor rocks,the thickness of the overlying bedrocks and other factors have been analyzed comprehensively.Gas content and gas emission in Yangcheng area have been predicated,and the contour map which showing gas content and emission of the whole coal well has been made as well.It is showed that Yangcheng coal mine is a low gas content mine.The change of gas content is mainly related to the depth of coal layers.Accompanying with thickness of overlying bedrocks and the increase of the depth of coal layers,the gas content and emission have a rising trend from north to south part in this area.
