摘要
以支塘向斜位于贵州重要的煤炭基地织纳煤田西北部,煤炭资源量高达2.85×109 t,煤层变质程度高,以无烟煤为主。文章基于保存较为完整的纳雍以支塘向斜区域地质特征分析,剖析了煤层组成,煤层气含量及煤层气成分等分布差异,对主要煤层M6的煤层特征、瓦斯含量及组成、煤层气资源量等进行估算,获得M6煤层的煤层气资源量为57.53×108 m^3,并认为向斜轴部含气量高于翼部。
The Yizhitangxiangxie is located in the northwest coal field of the important coal base in Guizhou,the coal resources amount to 2.85×109 t, the coal seam has a high degree of metamorphism, mainly anthracite.Based on the analysis of the regional geological characteristics of the Syncline in Nayong, this paper analyzed the composition of coal seam, the content of coalbed methane and the distribution of coalbed methane, estimated the coal seam characteristics, gas content and composition, coal seam gas resources and so on in the main coal seam M6, obtained the amount of coal-bed methane resources in M6 coal seam is 0.58×1010 m3,and that the gas content is higher than the axial part of the syncline wings.
