Abstract：In preliminary design phase,the occurrence condition of coal resources and coal sample from different coal seams of Hongliu shaft area in Ningdong were analyzed and predicted,and according to coal quality characteristics of actual driving seam, the coal quality changes and comprehensive utilization methods were discussed.The research shows that, Hongliu shaft area structure is medium,the occurrence of coal seam is stable,the main workable seam is relatively thick,the coal reserves are rich,the coal quality of workable seam is good,the coal is the low-moisture content,low ash,medium-low sulfur,medium-high volatile matter and high calorific value non caking coal,taking it as coal for fuels and energy or for chemical raw materials will be suitable.
