摘　　要：通过总结分析太行山东麓28对矿井的瓦斯含量特征与太行山东麓主要构造特征,揭示了地质因素(褶皱、断裂、岩浆侵入、埋深和顶底板等)对瓦斯赋存的控制作用,发现太行山东麓以鼓山-紫山背斜为界,大致呈现"西低东高,南小北大"的态势,东西不同的构造和埋深是造成瓦斯含量"西低东高"的主要控制因素,而"南小北大"主要是由岩浆岩自南向北侵入程度加剧造成的。This paper summarizes and analyzes the gas content features of 28 pairs of coal mines and the main structural features of Eastern Taihang mountain. The control action of geological factors （ folds, faults, magmatic intrusion, buried depth and roof and floor, et al） on the gas occurrence is revealed. It is found that taking Gushan - Zishan anticline as the boundary, the trend of Eastern Taihang mountains is roughly ＂ West low East high, South small North big ＂. Different tectonic and buried depth of East and West are the main controlling factors of causing the gas content ＂West low East high＂. The trend of ＂South small North big＂ is mainly caused by intrusion degree aggravating of the magmatic rocks from South to North.
