| 摘 要： | 煤层气组分浓度异常蕴含着丰富的地球化学成因信息,某些有害组分的异常浓度往往会对矿工人身健康造成影响。为此,基于相关文献和资料从重烃浓度异常、氧化物气体浓度异常、硫化氢浓度异常三个方面总结了国内外研究进展,分析了关于煤层气组分浓度异常地球化学成因的种种假说,认为目前对煤层气组分浓度异常的成因尚欠深入理解,有必要结合具体实例开展解剖研究,并从新的视角予以探讨。

| Abstract: | The concentration anomaly of CBM components contains abundant geochemical genesis information; while anomalous concentration of some harmful components will impact miner＇s health. Ad hoc, from three aspects of heavy hydrocarbon, oxide gas and hydrogen sulfide concentration anomalies on the basis of related documents and data, summed up research progress both at home and abroad. Analyzed a variety of hypotheses with regard to geochemical origin of CBM component anomalies, considered that the question for discussion is still short of comprehension or understanding at present, it is necessary to combine concrete specific examples and carry out dissecting analysis to discuss the issue from new angle of view. |
