Main Minable Coal Quality Features and Clean Utilization Orientation in Renjiazhuang Coal Mine,Ningxia
Renjiazhuang Coal Mine is located in the Hengcheng mining area,east of Ningxia Coal Field.The main coal-bearing strata are Taiyuan Formation and Shanxi Formation.In this study,the characteristics and distribution of coal composition,such as total moisture,sulfur content and ash content in No.3,5,6 and 9 coal seams are systematically analyzed by the method of statistics,and the degree of coal cleanliness and gasification characteristics are divided.The research shows that No.3 coal seam is good-medium clean coal,and the coal mainly used for gasification of coal water slurry and dry coal powder.No.5 coal seam is good-medium clean coal and mainly used for coking coal for utilization After washing and processing.No.6 coal seam is excellent-good clean coal and mainly used for coking coal for utilization After washing and processing.No.9 coal seam is good-medium clean coal and mainly used for gasification of coal water slurry and dry coal powder.
