Porous granular ammonium nitrate fuel oil explosive and preparation method thereof

Abstract

The invention discloses a porous granular ammonium nitrate fuel oil explosive, and also discloses a preparation method of the porous granular ammonium nitrate fuel oil explosive. The method has the advantages that 1, by adding the waste activated carbon adsorbed with mineral oil steam and TNT, the activated carbon and substances adsorbed by the activated carbon can be used as a reducing agent in the porous granular ammonium nitrate fuel oil explosive and can replace a part of diesel oil, the use amount of the diesel oil is reduced, and the effect of saving energy is achieved; 2, the waste activated carbon is used as a preparation raw material of the porous granular ammonium nitrate fuel oil explosive, so that the treatment problem of the waste activated carbon can be solved, the treatment cost of the waste activated carbon is reduced, and harm generated in the treatment process of the waste activated carbon is avoided; according to the invention, waste can be turned into wealth, and the production concept of long-term sustainable development is met; 3, the waste activated carbon is granular, so that the free-running property of the porous granular ammonium nitrate fuel oil explosive is not influenced after the waste activated carbon is added as a raw material, and on-site mixed loading is facilitated; and 4, the detonation velocity, brisance, work capability and other properties of the porous granular ammonium nitrate fuel oil explosive can be effectively improved.

Description

Technical field: [0001] The invention relates to an explosive and a preparation method thereof, in particular to a porous granular ammonium oil explosive and a preparation method thereof. Background technique: [0002] Ammonium oil explosive refers to a powdery or granular explosive mixture composed of ammonium nitrate and fuel, which is mainly suitable for open-air blasting projects without the risk of methane and mine dust explosions. Products include: powdered ammonium fuel explosive, porous granular ammonium fuel explosive, heavy ammonium fuel explosive, granular viscous explosive, and viscosified granular ammonium fuel explosive. Porous granular ammonium oil explosive is prepared by mixing 94-95wt% porous granular ammonium nitrate as an oxidant and 5-6wt% combustible diesel oil. It has the advantages of wide source of raw materials, good fluidity, simple processing, and highly mechanized mixing at the blasting site. , so it is widely used in the field of engineering bl...
