贵州黔西龙场煤矿煤层气资源及开发利用价值

Distribution,Development and Utilization of CBM from Longchang Coal Mine in Qianxi County,Guizhou Province

贵州黔西煤炭资源非常丰富,具有可采煤层多、煤层稳定、煤质较好、煤层瓦斯含量较高等特征,通过对黔西龙场煤矿钻孔勘探资料的分析,及煤层含气量的测试,分别预测了主采煤层的煤层气资源量,并根据区域主采煤层钻孔含气量编制了矿区煤层的煤层分布等值线图,为开发利用该区域煤层气资源提供了重要的基础资料。

Coal resource is abundant in Qianxi County,Guizhou Province.The coal measures in this area present the characteristics of steady thickness,multi-coal seams,abundant CBM and well quality.CBM volumes of main coal seams were estimated based on the gas content test.Sediment data of 11 wells in the coalfield were used.Additionally,CBM distribution maps of the main coal seams in the coalfield were charted.The study would supply important data for the development and utilization of CBM resource.
