山西沁水煤田煤炭生物气化特征分析概述

Overview of Coal Biogasification Characteristics Analysis of Qinshui Coalfield in Shanxi Province

煤层产甲烷菌菌群是一种由多种微生物组成且能够利用煤中有机物作为碳源,将煤从固态形式转为以甲烷为主的气态形式的独特微生物群落。通过一系列研究发现,在沁水盆地早期成气阶段生物成气具有一定的重要性。如今在特定条件下能够将该种处于休眠状态的菌群重新激活,并且能够再次实现生物甲烷合成。其中沁水煤田的地质特征和产甲烷菌菌群的生存特点揭示了山西沁水煤田的生物气化特征。

Coal seam methane producing bacterial community is a unique microbial community composed of multiple microorganisms that can utilize organic matter in coal as a carbon source to convert coal from solid to methane dominated gaseous form.Through a series of studies,it has been found that biogenesis plays a certain role in the early gas generation stage of the Qinshui Basin.Nowadays,under specific conditions,the dormant bacterial community can be reactivated and biomethane synthesis can be achieved again.The location characteristics and survival characteristics of methane producing bacteria in Qinshui coalfield reveal the biogeochemical characteristics of Qinshui coalfield in Shanxi Province.
