矿井气
煤田的煤层气与渗入煤层的井巷空气的混合气体
煤田成煤过程中，受到地质构造变迁的物理作用和复杂的生物化学作用，生成以甲烷为主要成分的煤层气，它以游离状态和吸附状态赋存于煤层及其围岩的孔隙中。经过漫长的地质时期，煤层气大部分已逸散至大气，仅有少部分残留于煤层中。由于煤田地质构造和成煤变质程度不同，不同煤田中煤层气储量悬殊，从而由煤层气次生的矿井气产量也有很大差异。

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.
