Liupanshui water city in the production of coal mine through the scene to take samples, analysis of water city mining area in the production of coal seam coal rock coal quality characteristics, combined with the classification standard, calculate the corresponding proportion score, with reference to the evaluation system, analysis of the clean and efficient use of coal direction. The research shows that the coal rock characteristics of Shuicheng mining area are mainly vitrinite, and the coal types are fat coal and coking coal. Coal quality characteristics, ultra-low ash coal-low ash coal-medium ash coal, low volatile-medium volatile, ultra-low sulfur coal-low sulfur coal-medium sulfur coal, no caking, medium flow temperature, with ultra-low fluorine, chlorine, mercury, arsenic, phosphorus characteristics, suitable for atmospheric fixed bed gasification, fluidized bed gasification, metallurgical coke and other coal. The content of SiO2+AL2O3+Fe2O3 in fly ash is more than 70%, which is suitable for mixing fly ash for mortar and concrete and cement active mixing materials.
