摘要

织纳煤田是贵州重要的煤炭基地,煤炭资源量高达2.22×1010t,煤层变质程度高,以无烟煤为主,煤层气资源量为1.6×1012m3。基于保存较为完整的织金牛场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M13、M15、M21、M29、M32及M34的煤层特征、瓦斯含量及组成、煤层气资源量等进行估算,获得可采煤层的煤层气资源量为18.39×108m3,并认为向斜轴部含气量高于翼部。

Abstract

The coal resource is abundant in Zhijin-Nayong Coal Field,Guizhou Province.The coal resource is up to 2.22×1010t.CBM resource in the Zhijin-Nayong region is up to 1.6×1012m3,which is because that coal measure with high metamorphic degree is favourable for CBM formation.In this paper,on the basis of the characteristics of coal measure,and the content and component of some main coal measures(M13,M15,M21,M29,M32,M34),CBM resource of Niuchang syncline,Zhijin,Guizhou was studied in detail.The result shows that CBM resource in the coalfield is up to 18.39×108m3,and that CBM resource in central syncline is more than that in the wing of syncline.
