摘　　要：通过系统的井下采样和测试分析,研究了山西省石炭二叠系主采煤层中汞元素的含量及分布特征,划分了山西省高汞煤的分布区域。结果表明,太原组主采煤层煤中汞含量为0.029×10^-6~1.629×10^-6,均值为0.250×10^-6;山西组主采煤层煤中汞含量为0.013×10^-6~1.497×10^-6,均值为0.276×10^-6;整体上,太原组主采煤层煤中汞含量均值高于山西组。Based on the systematic sampling,test and analysis of coal samples,studied the content and distribution of mercury in main coal seams of permo-carboniferous in Shanxi and delineated the distribution areas of high-Hg coals.The results show that the range of mercury content in main mining coal seams of Taiyuan formation is from 0.029×10^-6 to 1.629×10^-6 and the average is 0.250×10^-6;the range of mercury content in the main coal seams of Shanxi formation is from 0.013×10^-6 to 1.497×10^-6 and the average is 0.276×10^-6.Overall,the average mercury content in main mining coal seams of Taiyuan formation is higher than that in Shanxi formation.
