Locale vehicle made emulsification blasting agent underwater demolition

Abstract

The invention relates to a field vehicle-made emulsion explosive suitable for underwater blasting, belonging to a technical field for preparing the emulsion explosive. The emulsion explosive is mainly prepared by applying water-phase materials of ammonium nitrate, sodium nitrate and perchlorate water; oil-phase materials of emulsifier and diesel oil; density modifier of glass or plastic hollow bead; and dry powder of coarse aluminum powder and fine aluminum powder. Compared with traditional emulsion explosive, the field vehicle-made emulsion explosive of the invention has the advantages of high detonation velocity, big power and good water-resistant performance; the emulsion explosive is beneficial to solve the problem that the existing emulsion explosive is unsuitable for underwater blasting; the emulsion explosive has high application value in a large-scale underwater blasting project.

Description

technical field [0001] The invention relates to an emulsion explosive used in blasting operations, in particular to an on-site vehicle-made emulsion explosive suitable for underwater blasting. Background technique [0002] Traditional domestic emulsion explosives have a certain waterproof performance, but after soaking in deep water for a long time, the explosive performance attenuates greatly, and the detonation velocity is generally between 3500 and 4500m / s, which is difficult to meet the performance requirements of explosives for blasting in deep water. In addition, the blasting efficiency of traditional emulsion explosives is low, and problems of broken charges and hole jams often occur in deep water blasting, which seriously affect the construction quality and progress of charge blasting. Contents of the invention [0003] The object of the present invention is to provide a vehicle-made emulsion explosive with high detonation velocity, high power and strong water resi...

Problems solved by technology

[0002] Traditional domestic emulsion explosives have certain waterproof performance, but after soaking in deep water for a long time, the explosive performance attenuates greatly, and the detonation velocity is generally between 3500 and 4500m / s, which is difficult to meet the performance requirements of explosives for blasting in deep water

In addition, the blasting efficiency of traditional emulsified explosives is low. In deep water blasting, broken charges and hole jams often occur, which seriously affects the construction quality and progress of charge blasting.
