Abstract

FIELD: blasting operations. SUBSTANCE: invention may be used when mining mineral resources, laying roads, building water-development works and so on. In agreement with process hole is drilled, is charge with explosive with simultaneous insertion of hollow cones connected in pairs by common base. Vertexes of cones are displaced relative to vertical axis of hole. Twin cone forms two opposite flows of products of blast enhanced by shaping effect. With focusing of energy of such cones gas dynamic jet directed perpendicular to hole axis facilitating break of rock at point of concentration of flow of gas is formed. EFFECT: formation of explosive charge ensuring specified degree of crushing by control of energy characteristics of blast.
