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 profile measurement device for measuring the surface profile of the burden charged into the furnace through the rotating chute; and a tilt angle control device for controlling the tilt angle of the rotating chute. 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 has at least one of: 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, and for, on the basis of the obtained surface profile, instructing the tilt angle control device to change the tilt angle of the rotating chute being rotated; a calculator for instructing the speed control device to change the rotational speed of the rotating chute being rotated; and a calculator for instructing the speed control device to change the supply speed of the burden supplied to the rotating chute being rotated.
