PROBLEM TO BE SOLVED: To correctly monitor the operational condition of a blast furnace, and to predict any operational abnormality such as channeling. SOLUTION: The distribution condition of the measurement data collected by a plurality of sensors installed on a blast furnace facility is arranged on the two-dimensional plane or three-dimensional space reflecting the installation positions of each sensor on the blast furnace facility, the pattern formed by the measurement data using isopleths or the like, and the pattern or the characteristics information of the pattern is operated by the image processing. The operational condition of the blast furnace is monitored by comparing the obtained pattern or characteristics information of the pattern with the preset pattern or characteristics information of the pattern, the pattern or characteristics information of the pattern is updated corresponding to the temporal transition of the measurement data, and any operational abnormality of the blast furnace such as channeling is predicted by comparing the temporal transition with the transition condition of the preset pattern or characteristics information of the pattern.
