METHOD FOR OF BUILDING OR STRUCTURE Russian patent published in 2008 - IPC F42D3/00 

FIELD: exploding equipment, applicable at demolition of structural objects.

SUBSTANCE: the inner space of building 1(B) or structure (S) is isolated from the exterior by overlapping of through air passages 2 with the aid, for example, of polyethylene film 3 and filling of it with vapor. Then, explosive charges 6 are blasted. At a demolition of a building or structure their structural units wetted from the inside by water condensate practically do not give off any dust from the inside, and the dust formed at demolition of the unwetted parts of the building and structure is suppressed due to additional condensation of water vapor displaced into the atmosphere from the inner space of the building or structure on the dust particles of the secondary cloud. Filling of the gap between the external surface of the building and structure and the sealing shell with vapor makes it possible to accomplish wetting of the external surface of the building and structure by water condensate.

EFFECT: enhanced efficiency of dust suppression at demolition of the building and structure.
