| 摘 要： | 以“中国煤种资源数据库”为基础,结合新采集煤样,对中国不同煤田2237个煤层煤样的硫含量数据进行了统计分析,分不同时代、不同地域和不同煤种讨论了中国煤中硫的分布特征,并总结了煤中硫的分布规律.认为中国煤中硫的含量分布与成煤时代、聚煤地区密切相关.引入“储量权重”概念,按聚煤区储量加权计算,中国煤中平均硫含量为1.02%,该数值比算术平均值(1.40%)更能准确地反映中国煤中硫的含量分布.

| Abstract: | The sulfur content in coals of China was studied based on 2 237 coal samples from Chinese Coal Resource Database. The distribution of sulfur in the coals from different geological ages, different coal-accumulation districts, different provinces and different classes of coals were discussed. The study shows that the content and distribution of sulfur is influenced by geological ages and coal-accumulation districts. The concept of "weighted reserves" is presented in this paper, so the weighted mean content of sulfur in Chinese coal is 1.02% based on coal-accumulation districts reserves. The weighted mean is more accurate than the arithmetical mean (1.40%) to reflect the distribution of sulfur. |
