FIELD: blasting, in particular, construction at dismantling of building constructions at their caving. SUBSTANCE: invention is a method for dismantling of objects at their caving by means of extended shaped Quasar-charges by placing them in contour of the caved object in one or several continuous or interrupted in separate points threads of charges inside and/or outside the object in its lower part. EFFECT: enhanced efficiency of operations, reduced labour content and cost, enhanced safety and improved ecology. 7 cl
