Abstract

The invention discloses a porous mixed ammonium nitrate explosive which comprises the constituents (by weight percent) of porous ammonium nitrate 10-50% and powdery emulsified explosive 50-90%. The invention realizes good water resistance, high explosion speed and better explosion property.

Description

technical field [0001] The invention relates to an industrial ammonium nitrate mixed explosive, in particular to a porous granular ammonium nitrate mixed explosive used in the civil explosive industry. Background technique [0002] The explosives used in the civil explosive industry mainly include ammonium oil explosives, emulsion explosives, and ammonium ladder explosives. Ammonium-ladder explosives have better explosive performance, but have toxic components, are harmful to human body, and have high cost. Porous granular ammonium oil explosive is an industrial explosive widely used in open-pit mine blasting. Because of its low cost and simple production process, it is favored by users. But it also has disadvantages such as not being resistant to water, low blasting velocity, not suitable for small hole blasting and hard rock blasting. [0003] Powdery emulsion explosive is a high-performance industrial explosive with certain water resistance, which can be applied to vari...
