湖南省煤炭资源是华南九省较好的省之一,有涟邵,郴耒、桑石、黔淑、韶山、茶醴、资汝、祁零八大煤田,其中以涟邵、郴耒煤田甲烷资源丰富。煤层甲烷丰富的控制因素是煤层变质程度高、煤层厚、煤质灰分<20％挥发分<10％、煤层埋藏深、煤层顶底板透气性低、背斜构造、地下水活动弱等。涟邵、郴耒煤田煤层甲烷的生、储,盖组合条件尚属有利,是湖南省煤层甲烷资源的两大远景区,预测其甲烷总量达550亿米~3。
Coal resources in Hunan Province is one of the better provinces in nine provinces of South China, including Lian Shao, Chen Sha, Sang Stone, Guizhou Shu, Shaoshan, Chali, Ziru and Qilu Baidao Coalfields. Among them, Methane is abundant in resources. Coal seam methane richness is controlled by high degree of coal seam metamorphism, seam thickness, coal ash <20% volatile <10%, deep coal seam, coal seam roof and floor ventilation is low, anticline structure, weak groundwater activity. The combination of raw, reservoir and cap assemblage of coal seams in Lianshui and Chentai coalfields is still favorable. It is the two major prospects for methane resources in coal seams in Hunan Province. The total methane output is predicted to reach 55 billion m 3.
