Discussion on the Coal Quality Characteristics and Green Utilization of No.5#Coal Seam in Wangwa Mining Area
By comprehensively sorting out the coal quality data of the coal resources in Wangwa Mining area,aiming to promote the clean and efficient utilization of high-quality coal resources in Wangwa Mining area,taking the No.5#coal seam of Yan'an Formation as the research object,using the data analysis of previous coal geological exploration combined with systematic sampling and testing.The corresponding coal quality characteristics of the coal seam are studied in detail.The coal seam of Wangwa mining area has the characteristics of high vitrinite content and low inertinite content,mainly low to ultra-low ash,medium-low sulfur,medium-high volatile,mainly long-flame coal and non-caking coal;According to the type of clean utilization of coal,most of the coal is suitable for gasification and indirect liquefaction based on gasification,a small scale in northwest has the potential of direct liquefaction;The clean grade of raw coal isⅢ,which is relativly clean coal.The clean grade of floating coal isⅡ,which belongs to good clean coal.
