Abstract: 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.
