Injected water-resistant booster explosive used for seismic explosive column

Abstract

The invention particularly relates to an injected water-resistant booster explosive used for a seismic explosive column, and belongs to the technical field of explosive materials. The injected water-resistant booster explosive used for the seismic explosive column is safe, high in efficiency and low in cost. According to the technical scheme, the injected water-resistant booster explosive used forthe seismic explosive column comprises a shell, a detonator base, a main charge and an initiation system, wherein the shell is a cylindrical structure, one end of the shell is open, and the other endof the shell is provided with a detonator base insertion hole; the detonator base is arranged in the detonator base insertion hole in a matched mode, and the main charge and the initiation system areplaced in a cavity formed by the shell and the detonator base; and the initiation system is of a cavity structure, one end of the initiation system is closed, the other end of the initiation system is provided with an explosive injection hole, and an initiating explosive is arranged in the cavity structure of the initiation system. According to the injected water-resistant booster explosive usedfor the seismic explosive column, cheap expired explosives are used as the main charge of the injected water-resistant booster explosive, so that the product cost is reduced; and the injection processis adopted, so that the safety of the booster explosive is ensured.

Description

technical field [0001] The invention relates to the technical field of blasting equipment, in particular to an injection-filled water-resistant booster charge for a seismic source charge. Background technique [0002] The structure of the seismic source charge in the prior art is composed of three parts: the shell, the main charge, and the booster charge. The product has a detonator hole. Explosives can achieve the overall explosion of the seismic source powder column, and the explosion of explosives can be used as a seismic source for geophysical exploration such as oil, natural gas, coal, and minerals. [0003] Due to the requirements of charge density, detonation velocity, and power, etc., the seismic source charge products are made of a mixture of various explosives. The main charge itself has no detonator sensitivity and must be detonated by the booster charge. . In the past, the process of press-packing products of explosive boosters was to put a certain amount of ma...

Problems solved by technology

Due to the density of the press-packed TNT explosive column product, during the product storage and transportation, the drug block is prone to drop due to vibration, which reduces the explosive transmission performance of the product, and the price of TNT raw materials continues to rise, making the source explosive column used for transmission The cost of explosive column products continues to increase, which seriously affects the production efficiency of products
