摘　　要：为了探明二道岭矿区煤层瓦斯赋存规律,通过实测煤层瓦斯含量,以瓦斯地质理论为基础,分析了二道岭矿区煤层瓦斯赋存的控制因素。结果表明:岩浆热变质是矿区瓦斯含量普遍较大的根本原因;矿区构造和煤层埋深是控制瓦斯分布状况的直接因素。In order to study the coal seam gas occurrence law in Erdaoling mining area,through the measurement of coal seam gas content,on the basis of the gas geological theory,controlling factors of coal seam gas occurrence are analyzed.The results show that the magma thermal metamorphism is the root reason of gas content generally larger;the geological structure of mining area and coal seam buried depth are direct reasons of the gas distribution.
