Abstract: The distributive regulation of sulfur in coal is discussed on the basis of sedimentology, coal forming environment, geochemistry, etc. in this study. And the relationship between the coal forming environment and sulfur in coal is clarified in detail. The study indicates that the occurrence information of sulfur in coal is not only influenced by coal accumuating environment, but also by roof depositional environment. The coal forming environment has laid a foundation of sulfur occurrence in coal, while roof depositional environment is important and key link to make coal with high sulfur. The roof depositional environment of brackish muddy water tidal flat leads to high pyritized sulfur in underlying coal while that of clean marine water tidal flat leads to high organic sulfur in underlying coal.
