PROBLEM TO BE SOLVED: To provide a method for evaluating properly conveyability of pulverized coal to be blown into a metallurgical furnace such as a blast furnace or into a combustion furnace such as a boiler by utilizing an NMR method. SOLUTION: In this conveyability evaluation method of the pulverized coal, a nuclear magnetic resonance spectrum of<SP>27</SP>Al or<SP>29</SP>Si existing in the coal is measured, and the chemical form of an inorganic mineral mainly composed of Al and Si existing in the coal is classified based on the measured spectrum, and the conveyability of the coal is evaluated based on the classification.
