A floor surface blasting apparatus is used for removing rustproof coating (blasting) on a tank bottom surface to inspect weld lines on the bottom surface of high-capacity fuel tank. The floor surface blasting apparatus comprises a work arm which has weld line detecting sensors for detecting a weld line at the tip end and also has a blast head incorporating a suction nozzle; a work carriage which has the work arm and magnet devices incorporating a magnetic substance and travels arbitrarily on the floor surface; a transfer carriage which has a blast device for supplying blasting material to the blast head and travels arbitrarily on the floor surface; and a control device which controls the blast head so that the blast head is positioned on a weld line in accordance with the detection signal from the weld line detecting sensors and the signal of a position detecting device for detecting the position of the blast head and also makes the transfer carriage follow the work carriage.
