PURPOSE: A method for predicting the fluidity of coal for making cokes is provided to simply and accurately predict the fluidity of the coal and to stably manage coke product quality. CONSTITUTION: A method for predicting the fluidity of coal for making cokes comprises: a step of collecting data relating to the fluidity of the coal; a step of analyzing statistic significance level of the collected data and selecting impact factors with correlation with the fluidity of the coal; a step of applying the selected impact factors to a stepwise regression method and drawing R-squared between the fluidity and impact factors; a step of analyzing the stepwise regression and selecting impact factors with high correlation with the fluidity of the coal among impact factors selected at a primary selection stage; and a step of predicting fluidity for predicting the fluidity of the coal. [Reference numerals] (AA) Fluidity measured value(LMF); (BB) Fluidity estimated value(LMF)
