Description

technical field

[0001] The invention relates to an explosive, in particular to a colloidal emulsion explosive for high-detonation-velocity deep-water blasting and a preparation method thereof. Background technique

[0002] In modern naval warfare and ocean development, blasting in deep water is widely used. For example, in modern naval warfare, it is often necessary to destroy underwater oil pipelines, water pipelines, underwater optical cables, cables, and underwater hydraulic structures. It is necessary to blast and remove sunken ships, abandoned oil well well pipes, and pile legs of water operation platforms; blasting reefs and deep-water cofferdams in the excavation of deep-water pipe trenches in marine development, construction of deep-water ports, and excavation of deep-water bridge pile foundation pits ; When drilling in oil wells and water wells, it is necessary to blast the drill pipe when the drill is stuck. These blasts are usually carried out in water tens of met...
