FIELD: blasting.
SUBSTANCE: method for collapse of building, which provides for explosion of charge rows arranged in walls between window openings, between upper 1 and lower 2 level of openings. Additional lower row of charges 3 is located below level of window opening 2 provided that distance from extreme charge 3 of this row to the nearest angle of window opening makes not more than half of collapsed building wall thickness, at the same time above rows of charges, there are additionally installed asymmetrically located charges 5 or groups of charges.
EFFECT: increased reliability and safety of blasting works.
