Abstract

The invention relates to a viscous and granular anfo (ammonium nitrate and fuel oil) explosive and a preparation method thereof. The explosive comprises the following raw material components in parts by weight: 93-96 parts of porous granulated ammonium nitrate, 4-7 parts of diesel oil, 0.15-0.25 part of powdered polyacrylamide, 4-6 parts of colloidal polyacrylamide and 4-7 parts of a waste emulsion explosive or an emulsion explosive matrix. The viscous and granular anfo explosive disclosed by the invention effectively uses the waste emulsion explosive or the emulsion explosive matrix, well solves the problems of safety treatment on the waste emulsion explosive or the emulsion explosive matrix, is simple in preparation process and convenient in production, and is convenient for large-scale production and application of blasting sites.

Description

technical field [0001] The invention relates to a viscous granular ammonium oil explosive and a preparation method, belonging to the technical field of industrial explosive preparation. Background technique [0002] In order to meet the needs of shallow hole or deep hole pneumatic mechanical charging, reduce the labor intensity of charging, reduce the amount of returned charge, and improve the utilization rate of the blast hole, people have developed a ladder sticky granular explosive. This kind of explosive is made of porous granular ammonium nitrate, diesel oil and viscous explosive agent. It has certain fluidity and suitable adhesiveness, and basically solves the problem of charge return in the charging process of pneumatic machinery. However, since the added viscous explosive contains 1 / 3 of TNT, it will inevitably cause harm to workers during production and use. In order to solve this problem, the Chinese patent documents "Leaderless Viscous Granular Explosive" (Applic...
