Problems solved by technology

However, the existing problems are that the charge density is small, the detonation sensitivity is low, and it is not conducive to the on-site blasting hole filling, etc., so it cannot meet the actual needs of some blasting projects.
[0013] At present, ammonium oil explosives and water-gel explosives are mixed to form explosives, and water-gel ammonium oil explosives with adjustable density, detonation sensitivity, fluidity or viscosity have not been reported.

Abstract

The invention relates to the technical field of industrial explosive production, and in particular relates to a water gel and ammonium nitrate fuel oil explosive and a production method thereof. The water gel and ammonium nitrate fuel oil explosive with adjustable density, initiation sensitivity, explosive property, free-running property or viscosity is produced from different special ammonium nitrate fuel oil explosives and water gel explosives according to different proportioning requirements, has the characteristics of economical production cost and the like, meets the actual demands of different blasting works, and especially solves the problem of difficult explosive filling in an upward blast hole. The research proves that the water gel and ammonium nitrate fuel oil explosive with the adjustable initiation sensitivity can ensure the safety of explosive filling in the on-site blast hole, provides a material basis and technical support for smooth national economy construction, generates good economic and social benefits, and has very good application and popularization prospects.

Description

technical field [0001] The invention relates to the technical field of industrial explosive production, in particular to a hydrogel ammonium oil explosive and a production method thereof. Background technique [0002] Water-gel explosives were first proposed by G.R.Cattermole of DuPont in the United States in 1972. It uses organic amine nitrate (such as methylamine nitrate) as a sensitizer on the basis of slurry explosives, and at the same time further uses and improves chemical cross-linking technology to produce explosives that can be detonated by ordinary detonators and have high detonator sensitivity. Explosives are water gel explosives. Its components mainly include oxidizing agents, combustible agents, sensitizers, gelling agents, crosslinking agents, surfactants and water. [0003] Water-gel explosives have excellent water resistance, long shelf life, high explosive power, stable performance, and easy processing, which make them have a wide range of applications, bu...
