ANALASIS OF THE HYDROGEN RELEASE FROM COALBED GAS, SOUTHERN QINSHUI BASIN
沁水盆地南部煤层气中氢气释放规律研究

In this work,some specimens of coal's gas were collected from southern Qinshui Basin,Shanxi Province of China,and measured with gas chromatography(GC).After systematic sampling and analysis,the result is confirmed that hydrogen and helium in the gas of coal bed universally are against methane in concentration.Relationship between hydrogen and the helium has specified regular pattern.The study also finds that higher percentages of hydrogen in the gas come from deeper coal seams.The studies contribute some of original findings that are expected to be valuable for understanding the mechanism of formation of hydrogen from native coal.
