本文从沉积学、成煤环境、地球化学等方面研究了煤中硫的分布规律，并详细阐明了煤中硫与成煤环境的关系。研究表明：煤中硫的赋存状况，不仅受成煤环境的影响，而且受其顶板沉积环境的影响。成煤环境奠定了煤中硫的分布基础，而顶板环境则是促使煤富硫、高硫的重要因素。微咸水浑水潮坪的顶板沉积环境，导致了下伏煤高黄铁矿硫，而咸水的清水潮坪顶板环境则导致下伏煤高有机硫 In this paper, the distribution of sulfur in coal is studied from aspects of sedimentology, coal-forming environment and geochemistry, and the relation between sulfur in coal and coal-forming environment is elaborated. The results show that the occurrence of sulfur in coal is affected not only by the coal environment but also by the deposition environment of the roof. The coal-forming environment laid the foundation for the distribution of sulfur in coal, while the roof environment is an important factor for promoting sulfur-rich and sulfur-rich coal. Brackish water muddy water tidal flat deposition environment, leading to the coal under high pyrite sulfur, and brackish water tidal flat roof environment led to the next coal high organic sulfur
