礦井氣
煤田的煤層氣與滲入煤層的井巷空氣的混合氣體
?
煤田成煤過程中，受到地質構造變遷的物理作用和復雜的生物化學作用，生成以甲烷為主要成分的煤層氣，它以游離狀態(tài)和吸附狀態(tài)賦存于煤層及其圍巖的孔隙中。經(jīng)過漫長的地質時期，煤層氣大部分已逸散至大氣，僅有少部分殘留于煤層中。由于煤田地質構造和成煤變質程度不同，不同煤田中煤層氣儲量懸殊，從而由煤層氣次生的礦井氣產(chǎn)量也有很大差異。

Mine gas
The mixed gas of coalbed methane in coalfields and the air seeping into coal seams
During the process of coal formation in coalfields, the physical and complex biochemical effects of geological structural changes generate coalbed methane, mainly composed of methane. It exists in both free and adsorbed states in the pores of coal seams and their surrounding rocks. After a long geological period, most of the coalbed methane has dissipated into the atmosphere, with only a small portion remaining in the coal seams. Due to the different geological structure and coal forming metamorphic degree of coal fields, the reserves of coalbed methane in different coal fields are very different, so the output of mine gas generated by coalbed methane is also very different.
