Abstract

FIELD: blasting operations. SUBSTANCE: additional charge is blasted, impact momentum is transmitted to the unloading element made of material, whose dynamic stiffness is lower than the dynamic stiffness of explosive in the main charge; the unloading wave moves into the main charge. Then, another additional explosive charge is blasted on the side of the unloading element; the time interval between blasts is determined by the moment of forming of unloading wave in the main explosive charge. EFFECT: enhanced safety of blasting operations.

Область применения: взрывные работы. Технический результат: повышение безопасности работ. Сущность изобретения: производят подрыв дополнительного заряда, ударный импульс передают на разгрузочный элемент, выполненный из материала, динамическая жесткость которого меньше динамической жесткости ВВ в основном заряде, при этом в основном заряде идет волна разгрузки. Затем со стороны разгрузочного элемента производят подрыв второго дополнительного заряда ВВ, интервал времени между подрывами определяется моментом образования волны разгрузки в основном заряде ВВ.Scope: blasting. Effect: increased safety. The inventive produce an additional charge, the shock pulse is transmitted to the unloading element made of a material whose dynamic stiffness is less than the dynamic stiffness of the explosive in the main charge, while the unloading wave is in the main charge. Then, from the side of the unloading element, a second additional explosive charge is blown up, the time interval between explosions is determined by the moment the unloading wave forms in the main explosive charge.
