摘　　要：峰峰矿区2#煤层瓦斯赋存呈现"西低东高、南小北大"的特征,探讨了地质构造、煤的变质程度及地下水活动等地质因素对煤层瓦斯赋存的影响。地质构造对矿区瓦斯赋存控制作用显著,是控制煤层瓦斯赋存的主控地质因素。鼓山两侧瓦斯大小的差异与地下水的活动差异密不可分,鼓山东侧瓦斯由南向北逐渐变大的原因是受岩浆活动引发煤变质程度的变化影响较大。The content of 2^#coal seam methane in Feng＇feng Mining Area is low in south and west,and the content is high in north and east. This paper discussed the influences of geological structure ,coal metamorphic degree and groundwater activity to the gas occurrence law. Geo- logical structure observably controlled gas occurrence,and it is the main factor that control the methane occurrence. The content of coal seam methane difference between the east and west of Gushan are closely related to groundwater activities. The reasons that the content of coal seam methane increasing from south to north in east of Gushan is caused by magmatic activities ,which changed the coal metamorphic degree.
