Abstract：In order to improve products quality in preparation of unsized raw coal,based on lump coal production index and technical pa-rameters of Yanzishan coal preparation plant as well as the mixing ratio of two kinds of raw coal,taking Jurassic and carboniferous raw coal in Datong coal mine as research object,establish and optimize dynamic control model between technical parameters and products quantity and quality.Forecast the dynamic change trend of product quantity and quality,lump coal separation density.The results show that the opti-mized production rate of lump coal,ash content,moisture content and calorific value optimization model of the correlation coefficient R in-crease by 0.07245,0.22410,0.15157,0.16059 respectively,lump coal production index dynamic control model is improved significantly. After regulation,the yield and calorific value of product increase by 1.10% and 0.45 MJ/kg,the ash decrease by 1.28%.The regulation re-alizes the effective control of coal products quality.
