Problems solved by technology

[0005] At present, explosive composite materials and explosive synthetic materials are all produced in open-air exposed charge bags, which have special requirements on the environment of the processing site, and there are blasting shock waves and noise problems.
These shortcomings greatly increase the production cost of blasting composite materials and limit the production scale of blasting composite materials

Abstract

The invention discloses a method for preparing an explosive cladding metal bar. The method comprises the process steps that holes are distributed in water-free pre-blasting rock (1) of a strip mine step according to designed blast hole net parameters to form a water-free dry vertical blast hole (2); a cladding metal bar preparing device (3) is placed in the middle position of the bottom of the blast hole (2); explosive (6) is loaded in the blast hole (2) and plugged with tamping plug (7); and the explosive (6) is detonated, under extrusion of blast energy, a B-metal material pipe and an A-metal material solid bar are compounded, and the explosive cladding metal bar is prepared. The cladding metal bar preparing device (3) comprises the A-metal material solid bar, a preserved air gap, the B-metal material pipe and a protection layer from inside to outside in sequence. New explosive cladding material products are manufactured in the mine blasting exploitation process, one blast hole has multiple purposes, and the newly-increased economic benefits of enterprises are increased under the condition of not influencing the blasting effect.

Description

technical field [0001] The invention belongs to the technical field of composite metal material preparation, and in particular relates to a process for preparing composite metal rods by using an explosive composite method, which is especially suitable for preparing explosive composite stainless steel rods during blasting operations in open-pit mines, and can not only significantly improve the energy utilization rate of explosives , and at the same time, under the premise of not affecting the blasting effect, "one hole with multiple functions" is realized, creating good economic benefits. Background technique [0002] Explosive composite material preparation technology is a new type of processing technology in the field of explosive processing. It is prepared by using the explosive composite method to use the huge energy generated by the explosion of explosives to realize the jointing of similar or different metal plates. It has advantages that cannot be compared with traditio...
