摘　　要：在对国内外硫化氢成因研究及同位素研究分析对比的基础上,提出了煤矿硫化氢形成的硫酸盐生物还原(BSR)、热化学硫酸盐还原(TSR)和岩浆作用三大成因类型及其识别特征。对煤层H2S生物化学降解及热解成因进行了讨论,分析了煤层H2S的富集规律,并对国内外一些H2S矿井的成因类型进行了分析归类,提出了煤岩层H2S气体的研究方向。Based on domestic and overseas researches on the genesis of hydrogen sulfide and the comparative analysis of sulfur isotopes,presented three genesis modes of hydrogen sulfide,bacterial sulfate reduction（BSR）,thermochemical sulfate reduction（TSR） and igneous activity,as well as the characteristics for identification.H2S caused by biochemical decomposition and pyrolysis in coal seams was discussed,and its distribution in coal seams was analyzed.And meanwhile,analyzed and indentified the genesis modes of some hydrogen sulfide coal mines both in China and abroad,and put forward suggestions of future research.
