摘要

研究了沁水盆地南部煤层气样品中氢气的释放规律,发现煤自然释放的氢气和自然释放的氦气与甲烷之间在同一个勘探区范围内存在规律性,表现为煤层瓦斯中氢气含量变化趋势与氦气含量变化趋势呈正相关,与甲烷含量变化趋势呈负相关。结合煤田地质资料分析,还揭示了在同一个勘探区内煤层瓦斯中的氢气含量与含氧量、含水量及煤变质程度的关系。

Abstract

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.
