Composite liquid rock breaking rod used for generating controllable shock waves and manufacturing method of composite liquid rock breaking rod

Abstract

The invention relates to a composite liquid rock breaking rod used for generating controllable shock waves and a manufacturing method of the composite liquid rock breaking rod, and aims to solve the problem that mining of mineral resources is restricted due to the defect that the electric energy storage density is low when the the mineral resources are mined through metal wire electric explosion.According to the composite liquid rock breaking rod used for generating the controllable shock waves, a shell and an inner pipe are both hollow straight pipes with two closed ends, the shell sleeves the inner pipe coaxially, the outer diameter of the shell is 35-40 mm, the length of the shell is 380-430 mm, a metal wire is arranged along the axis of the shell and the inner pipe, the two ends of the metal wire extend out of the shell and are fixedly installed, powdery energetic materials fill the interior of the inner pipe, and liquid energetic materials fill the space between the inner pipe and the shell. The manufacturing method of the composite liquid rock breaking rod used for generating the controllable shock waves comprises the steps of preparing all components, assembling the metal wire, an inner pipe end and the inner pipe, filling the inner pipe with the powdery energetic materials and packaging the powdery energetic materials through the inner pipe end, assembling the inner pipe, an end cover and a straight pipe, and filling the straight pipe with the liquid energetic materials and packaging the liquid energetic materials through the end cover.

Description

technical field [0001] The invention belongs to the technical field of mining of mineral resources, and in particular relates to a composite liquid rock-breaking rod for generating controllable shock waves and a manufacturing method thereof. Background technique [0002] Mineral resources are an important material basis for economic and social development. At present, whether it is metallic minerals, non-metallic minerals or building stones, due to their high hardness, conventional tools have problems such as mining difficulties. Therefore, explosive blasting is mainly used in actual mining. . Although explosives and other pyrotechnic products have great technical advantages in rock breaking operations, explosive blasting and rock breaking not only pose a serious threat to the life safety of production personnel, but also have the disadvantage of poor environmental protection, which leads to the use of explosives for rock breaking mining. The regulations received are becomi...
