METHOD FOR MAKING MOULDED EXPLOSIVE CHARGES AND MOVING CONTROLLED MOLDING HEAD FOR IMPLEMENTATION THEREOF Russian patent published in 2016 - IPC C06B21/00 F42B33/02 

FIELD: blasting operations.

SUBSTANCE: invention relates to making moulded explosive (ES) charges. Method comprises filling the body with thin layers of the fused explosive, in series, one after another, after solidification of the previous layer. Process of solidification of each layer of the explosive is performed from the condition of deep mixture supercooling. Forming the explosive charge is performed continuously by means of moving, controlled molding head, its movement in horizontal and vertical planes is set based on the geometry of the charge and explosive charge is formed by thin horizontal layers, according to the mathematical charge model, loaded in the computer software, controlling the process, when each layer is formed, head or platform with the body are moved in vertical direction to the height equal to the layer thickness until the whole charge is formed. Movable controlled moulding head comprises a unit for supply of heated explosive melt and explosive melt cooling unit. Body of the melt supply unit is connected to control mechanism for movement and control of molding head directly in the area of forming layers inside the charge body.

EFFECT: in addition to high quality of produced charge, homogeneous structure, high density and absence of porosity, method enables to completely automate the process and increases charge producing efficiency.
