| 摘 要： | 运用煤岩学、煤化学、地球化学等学科的理论与方法，对湖南蒋家坪矿区煤质、煤岩特征和形态硫进行分析，结果显示：所测样品全硫含量为8％～10．1％，其中有机硫含量高达6％，属高有机硫煤；煤样的显微组分以镜质组为主，含量接近80％，惰质组中以丝质体、半丝质体和碎屑惰质体为主，矿物则多以黄铁矿和黏土矿物为主。通过对煤中成煤植物类型、凝胶化程度、镜惰比和氧化指数的研究，认为矿区高硫煤形成于比较潮湿的弱氧化条件下。

| Abstract: | To use theories and methodologies of coal petrology, coal chemistry, geochemistry and other branches of learning analyzed coal quality and coal petrologic characteristics and sulfur forms in the Jiangjiaping mine area, Hunan Province. The results have demonstrated that the total sulfur content is 8%-10%, in which, the organic sulfur content can be as high as 6% in tested coal samples, thus belongs to high organic sulfur coal. Coal macerals are mainly vitrinite, account for about 80% in total, while the inertinite is mainly composed of fusinite, semifusinte and inertodetrinite, minerals are mainly pyrite and clay minerals. Through studies of coal-forming plants, gelatinization extent, vitrinite/inertinite ratio and oxidation index considered that the high sulfur coal was formed under a rather humid, weak oxidizing environment. |
