PROBLEM TO BE SOLVED: To provide a blending method of fine powdery coke into sintering raw material, with which the fine powdery coke in the drying state can be utilized as the carbonaceous material for producing sintered ore. SOLUTION: When iron ore powder for producing the sintered ore is prepared by piling many kinds of descriptions of iron ore powder to many layers on a yard 5 whose bottom surface is formed as a rectangular shape, and uniformly mixing after discharging in the orthogonal direction to the axis of rectangular shape with a reclaimer, firstly, the dried fine powdery coke is charged into a mixer in the closing state, and after adjusting the moisture by mixing with the wet fine powdery coke 2 in the mixer, the layer 4 of the mixed fine powdery coke 3 having uniform thickness on the ground of the yard is formed and thereon, the iron ore powder is piled in order so as to perfectly cover the mixed fine powdery coke layer.
