Abstract

The invention discloses a viscous explosive without a single-compound explosive and a preparation method of the viscous explosive. The viscous explosive is prepared by mixing porous granular ammonium nitrate, expanded ammonium nitrate, light diesel oil and adhesives according to a certain proportion, wherein the expanded ammonium nitrate is prepared by mixing a water phase and an oil phase according to a certain proportion through vacuum drying, the water phase of the expanded ammonium nitrate comprises ammonium nitrate, sodium nitrate, a dispersing agent and water, and the oil phase comprises a solid composite oil phase and a liquid composite oil phase. The viscous explosive prepared by the method has the advantages that the viscous explosive has a certain fluxion property, certain cohesiveness and excellent explosion performance, the potential safety hazard caused by the adding of the single-compound explosive is avoided, the large explosive returning quantity and serious waste during explosive loading are avoided, an explosive loading environment is improved, the labor intensity of workers is lowered, the explosion requirements of upward holes of underground mines are satisfied, and evident economic and social benefits are achieved.

Description

technical field [0001] The invention relates to a viscous explosive, in particular to a viscous explosive without elemental explosive suitable for underground mine blasting and a preparation method thereof, belonging to the technical field of civil blasting explosives and its manufacture. Background technique [0002] Explosives used in underground mine blasting in the prior art are mainly powdered ammonium ladder explosives. Many underground mines use air-compressed charge machines to blow powdered explosives into blastholes. Shaped explosives cause the amount of returned powder to be as high as 10%-20%, so that the waste of explosives is very serious. For a long time, both shallow hole blasting and deep hole blasting have been manually charged, which is labor-intensive and the blastholes have not been fully utilized. [0003] In some underground mines, a certain amount of diesel is added to the powdered explosives for mixing to reduce the amount of rework, but on-site mix...
