运用瓦斯地质理论,结合地质勘探和矿井生产揭露的瓦斯地质资料,研究了艾维尔沟矿区的瓦斯地质规律.综合分析了地质构造、煤层埋深、构造演化、煤变质程度等对煤层瓦斯赋存的影响.提出了煤层埋深是艾维尔沟矿区煤层瓦斯赋存区域的主控因素,同时受构造演化、煤变质程度等因素影响,在局部区域受地质构造因素控制明显.因各种因素的共同作用,在沿煤层走向上,同一水平标高,矿区西部瓦斯含量最高,东部次之,中部最小;沿煤层倾向方向上,瓦斯含量具有随煤层埋深的增加而增大的整体趋势.在向斜构造轴部及断层带附近瓦斯富集.

According to the geological exploration and the gas geological data which are exposed in the mine production, the paper researches the gas-geology regularity of the Aiweiergou mining. This research also analyzed the effects of tectonic evolution, burial depth of coal seams, tectonic evolution, metamorphic grade of coal to the gas bearing. The research revealed that the main factor is the burial depth of coal seams, and the other factors are tectonic evolution, metamorphic grade of coal and part of the region is affected obviously by the tectonic. As the result, along the trend of coal seam gas content in the western mining is the highest, the eastern mining＇s secondary, and the central mining＇s the least. Along with the coal seam orientation direction, the linear relationship obviously can be found between the gas content and seam depth which the gas content increased with the increase of the coal burial depth.
