Provided is a blast furnace facility having a measurement means for accurately and quickly determining the surface profile of a furnace burden. This blast furnace facility comprises: a rotating chute for charging a raw material into the furnace through the top of the blast furnace; a plurality of tuyeres for blowing hot air and fine powdered coal into the furnace; a profile measurement device for measuring the surface profile of the burden charged in the furnace through the rotating chute; and a blown amount control device for controlling the blown amount of at least the hot air or the fine powdered coal in the tuyeres, wherein the profile measurement device has a radio range finder that is provided at the top of the furnace and that is for measuring the distance to the surface of the burden charged in the furnace, and a calculator for deriving the surface profile of the burden on the basis of furnace overall distance data relating to the distance, to the surface of the burden, determined by scanning detection waves of the range finder in the perimeter direction of the blast furnace.
