FIELD: ferrous metallurgy. SUBSTANCE: method involves making blast-hole in the object to be destroyed, by providing explosion of cumulative charge by cumulative jet; directing cumulative charge to mass center zone of object to be destroyed, with ratio of blast-hole diameter and length and cumulative charge diameter 0.2-0.4 and 2-6; positioning cumulative charge cut at a distance of (1-5) diameters of cumulative charge from object to be destroyed. EFFECT: increased efficiency by reduced blast-hole making time and enhanced reprocessing of large-sized wastes. 1 tbl
