Abstract

The invention relates to a water-in-oil emulsion explosive, which is characterized in that the explosive contains ethylene vinyl acetate copolymer, has good storage stability, and is not easy to produce explosives even if it is stored under a load for a long period of one year. Phenomenon of performance degradation and curing, only slight, easily disintegrating curing occurs partially, and is also very suitable for water since it can be filled with a filling machine even after long-term storage and has good water resistance hole blasting.

Description

technical field

[0001] The present invention relates to an explosive. Specifically, it relates to a water-in-oil emulsion explosive used in industrial blasting operations such as tunnel excavation, quarrying, and mining. Background technique

[0002] As industrial explosives used in blasting work etc., nitroglycerin explosives, aqueous explosives, ammonium nitrate explosives, ammonium oil explosives (hereinafter referred to as ANFO explosives) and the like are generally known. Among these explosives, aqueous explosives are widely used in industrial explosives because they do not contain gunpowder in their composition and are safer than conventional nitroglycerin explosives. Aqueous explosives can be classified into slurry explosives and emulsion explosives, among which emulsion explosives are characterized by good formability and weather resistance. Emulsion explosives have been variously improved since they were disclosed as water-in-oil emulsion explosives in US Pat. No....
