为揭示煤中有机硫的赋存状态及其地质成因，采用电子探针微区分析和硫同位素分析技术对华北地区山西大同、太原西山、霍州以及安徽淮南４ 个矿区的８ 层晚古生代的煤层进行了研究．海水的作用对有机硫的聚集起着十分重要的影响．煤的不同显微组分中有机硫的质量分数存在明显差异，镜质组中有机硫的质量分数高于其在惰质组的质量分数．硫在煤中的聚集是一个逐渐累积的过程，有机硫的聚集一般滞后于黄铁矿硫的聚集．泥炭沼泽条件控制着硫源和硫酸盐还原菌的活动性，进而影响了煤中有机硫质量分数的高低．凝胶化指数越大，有机硫的质量分数越高．植物结构保存指数与有机硫质量分数之间的对应关系不明显
In order to reveal the occurrence state of organic sulfur and its geological origin in coal, electron microprobe analysis and sulfur isotope analysis techniques were applied to the study on the 8th-layer Paleozoic in four coal mines in Datong of Shanxi Province, Xishan of Taiyuan, Huozhou of Huaihe and Huainan of North China Seam has been studied. The role of seawater plays an important role in the aggregation of organic sulfur. There were significant differences in the mass fraction of organic sulfur in different microscopic fractions of coal. The mass fraction of organic sulfur in vitrinite was higher than that in inertinite. Aggregation of sulfur in coal is a gradual accumulation process, where the accumulation of organic sulfur generally lags that of pyrite. Peat swamp conditions control the activity of sulfur sources and sulfate-reducing bacteria, thereby affecting the level of organic sulfur in the coal. The greater the gelation index, the higher the mass fraction of organic sulfur. The corresponding relationship between plant structure preservation index and organic sulfur mass fraction is not obvious
