EXPLOSIVE APPARATUS FOR DYNAMIC LOADING Russian patent published in 2021 - IPC F42D3/00 G01N3/313 

FIELD: blasting.

SUBSTANCE: invention relates to the field of blasting, namely, to small-sized loading apparatuses, and is intended for forming an explosive wave of a predetermined shape in a charge of an explosive substance (explosive) by synchronous detonation thereof with a minimum diversity by means of multipoint initiation. The explosive apparatus for dynamic loading comprises a main explosive charge, made multi-layered and in contact with an inert plate made of a material, the speed of passage of the shock wave wherein is less than the speed of detonation of the main charge explosive, the main charge initiation unit including a matrix with an intermediate charge of the explosive substance and a means of initiation thereof, a sublayer of the explosive substance with the thickness h, installed on the output surface of the initiation unit. A multipoint initiation former is used as the main charge initiation unit, wherein the matrix is made multi-layered, and the intermediate charge is made in the form of a network of detonation channels laid in all layers of the matrix of the initiation unit and branching. The branches of the end sections of the channels come to the surface of the explosive sublayer. The apparatus is equipped with a separator adjacent to the explosive sublayer and made in the form of an inert substance layer with a thickness Δ mm, determined from a ratio. The end sections of the detonation channels extend along the layers of the matrix of the initiation unit, and the amount thereof is the same on each layer. The layers of the matrix are arranged perpendicular to the main charge. The side surface of the main charge is made expanding in the direction of detonation propagation.

EFFECT: increase in the efficiency of operation due to the maximum decrease in the load diversity - the asymmetry of the surface of the detonation front formed in the main charge and due to elimination of the "cutting" impact on the loaded object of detonation of the main charge along the projection line of the side surface thereof.
