TY - JOUR PY - 2012// TI - Origin of hydrogen sulfide in coal seams in China JO - Safety science A1 - Liu, Mingju A1 - Deng, Qigen A1 - Zhao, Fajun A1 - Liu, Yanwei SP - 668 EP - 673 VL - 50 IS - 4 N2 - In recent years, coal mines in China have seen accidents caused by sudden release of hydrogen sulfide (H2S), with higher severity. Based on recent local and overseas research on the origin of hydrogen sulfide and the comparative analysis of isotopes, the paper presents three formation models of hydrogen sulfide: bacterial sulfate reduction (BSR), thermo-chemical sulfate reduction (TSR) and igneous activity, as well as the characteristics for identification. This paper analyzes and categorizes the formation models of some hydrogen sulfide in coal seams in China. Some suggestions were put forward for future research of H2S in coal mines in China.
