摘　　要：通过对大量钻孔数据和生产矿井实测资料的综合分析,基本探明了艾维尔沟煤矿区西部和东部的瓦斯含量高,中部含量低的特征。分析认为,构造演化环境是瓦斯的形成和含量多少的决定因素,煤层埋深、顶底板岩性、水文地质条件是影响瓦斯赋存的主要因素。通过综合分析,推断随着埋藏深度的增加以及逆冲断层附近,瓦斯含量均会增加。Through comprehensive analysis including a large number of borehole data and production mine measured data, the paper ba- sically proved the features that the gas content in West and East of Ewirgol Mining Area is high, low content in middle area. The analy- sis shows that tectonic evolution of environment is decision factor for gas formation and content, the buried depth of coal seam, roof and floor lithology, hydrogeological conditions are the main factors for gas occurrence. Through comprehensive analysis, the paper con- eludes that the gas content increases with the increase of buried depth and thrust faults.
