PROBLEM TO BE SOLVED: To provide a demolition method for a hollow tower-like structure which can prevent harmful substances from being scattered by a filling failure even if an inorganic curable fluid or the like is not sufficiently filled although a scattering covering layer with a moderate thickness for covering the harmful substances with the inorganic curable fluid such as mortar is formed. SOLUTION: A tubular form 3 is installed in the hollow tower-like structure (chimney) 1 wherein the harmful substances exist on an inner peripheral surface; the inorganic curable fluid 9 is filled into a space between the tubular form 3 and the hollow tower-like structure 1; and after the curing of the inorganic curable fluid 9, the hollow tower-like structure 1 including the tubular form 3 is cut in round slices in a circumferential direction. A plurality of injection holes 10 are formed in estimated cutting positions, respectively; a fire-resistant lining material 2 is impregnated with an immersion solidification agent 11 which is injected from the injection holes, and after the solidification of the immersion solidification agent, they are cut in round slices.
