| 摘 要： | 在系统分析矿井地质资料的基础上,结合矿井瓦斯实测参数,以区域构造演化和矿井构造的控制作用为主线,探讨了祁南矿煤层的瓦斯赋存规律及其控制因素。结果表明,本区受宿南向斜的控制,煤层瓦斯分布具有南高北低、东高西低、东南部最高的总体规律;宿南向斜转折端部位由于放射状正断层的发育,瓦斯含量相对较低。井田中部逆断层发育的次级褶皱区域,瓦斯含量相对较高;在-900m以浅,瓦斯含量与煤层埋深、煤级均表现出较好的正相关关系;较高的顶底板泥岩比例和半封闭的水文地质条件为瓦斯的保存提供了有利条件;Ⅱ、Ⅲ类煤厚度所占比例小于20%,渗透率大于1mD,表明煤层瓦斯具备较好的运移条件。

| Abstract: | Based on systematic analysis of mine geological data,combined with measured parameters of mine gas,with the mainline of regional tectonic evolution and mine structural control actions,discussed coal seam gas hosting pattern and its controlling factors in depth.The results showed that: due to controlled by the Sunan syncline,the coal seam gas has a general distribution pattern of higher in south than north,east than west and highest in the southeast.Lower gas content in the synclinal turning part is because ... |
