Abstract

Turpan-Hami Basin contains abundant coal resources and is an important part of large coal base in Xinjiang. In this study, the 4–2 coal seam of the Badaowan Formation in the Lower Jurassic in the Panji Coal Mine in the Turpan-Hami Basin is selected as the research object. Through systematic analysis of maceral, maximum reflectance of vitrinite, ash, volatile, sulfur, hydrogen carbon atomic ratio, chlorine, fluorine and arsenic elements in coal, combined with the evaluation index system of coal cleanliness grade and direct coal liquefaction, the clean potential and clean utilization method of the 4–2 coal seam are investigated. The 4–2 coal seam of Panji Coal Mine has the characteristics of relatively low chlorine and arsenic contents and relatively high ash, sulfur and fluorine contents. The high ash content is the main obstacle to the clean utilization of coal in Panji Coal Mine. The research results show that clean coal grade is of category III for raw coal, belonging to relatively unclean coal. The coal types of 4–2 coal seam are mainly composed of brown coal, long-flame coal, and non-caking coa, with relatively low inertinite content, extremely low-low ash, high volatile content and high hydrogen-carbon atom ratio. Floating coal meets the evaluation criteria for direct liquefaction coal and is suitable for use as class II direct liquefaction coal. The research results have important guiding significance for the clean and efficient utilization of coal resources in Panji Coal Mine.
