摘    要:洪山殿矿区煤炭资源丰富,是湖南省近期煤层气开发的优先靶区之一。矿区含煤地层为晚二叠世龙潭组上段,煤类以贫煤为主,含有少量无烟煤,煤层镜质组含量高,微裂隙发育,顶底板封闭性好,地下水活动弱,特别是区内向斜构造发育,都为煤层气的富集提供了条件。矿区煤层气井测量显示,煤层气平均含气量16.04m^3/t,属极富气煤层。根据矿区构造发育特征,认为在向斜转折部位和未被裂隙破坏的背斜顶部,煤层气相对富集,是今后勘探开发重点研究区域。

关 键 词:煤层气  富集条件  洪山殿矿区

Enrichment Conditions of CBM in the Hongshandian Coal Mining Area, Hunan Province

Abstract:The Hongshandian mining area is rich in coal resources. The primary coal bearing strata is the upper member of the Late Permian Longtan Formation. The coal is dominated mainly by lean coal and less by anthracite. The coal bed methane (CBM) content is very high, averaging 16.04m^3/t. This area has good geological storage conditions for CBM and will be one of the preferential targets for CBM development in Hunan Province. The main affecting factors of CBM enrichment are the folded synclinal structures, well developed cleats and fissures in coal, vitrinite-dominated coal macerals, higher coal ranks, better sealing ability of the roof and floor of coal beds, and simple hydrogeological conditions.
Keywords:CBM  enrichment condition: Hongshandian coal mining area
