摘要
河东煤田北部煤层中的硫含量主要取决于成泥炭环境。根据硫含量在垂向上的变化,可将13号煤分为三种类型。研究表明煤中硫的主要形式为黄铁矿硫(67.4％)和有机硫(30.6％)水介质中硫酸盐的浓度和pH值是影响煤中硫含量的主要因素。相关分析也表明某些煤灰成分同样与泥炭堆积环境有关。
Sulfur content in coal beds largely depends on the peat-forming environments. According to the vertical change of sulfur content, three types can be divided in the coal bed 13. The study shows that the principal forms of sulfur are pyritic (67.4%) and organic (30.6%). Corre-lation analysis indicates that the total sulfur is closely related to pyritic sulfur (r=0.84). The density of sulfate in the medium of water and pH value are the most important factors influencing the sulfur content in coal beds. The study also shows that some kinds of composi-tions or compounds in the coal ash are related to the depositional environments.
