AMMONIUM NITRATE-BASED EXPLOSIVE WITH A PART OF ORGANIC WASTE

Explosives are energy materials with a wide range of applications. In commercial applications, the most common are ANFO explosives, which contain mineral, diesel oil as fuel and granular ammonium nitrate as an oxygen carrier. The innovation, an explosive based on granular ammonium nitrate with a portion of organic waste, was innovated by replacing the mineral oil with shredded plant residues, i.e. hay. Furthermore, the specialty is in the way of mixing granular ammonium nitrate (AN) with fine particles of plant residues and achieving a stable coating of AN granules. This achieves the mechanical stability of the coated porous AN grains, that is, the permanent distribution of the fuel material and the explosiveness, that is, the detonability of the mixture. The explosive prepared in this way is a substitute for the classic ANFO explosive with very similar detonation characteristics, i.e. mining use properties. This excludes the use of diesel oil and includes the use of natural, harmless and available plant materials. Furthermore, with slightly lower values of detonation pressures, a satisfactory granulation of the mined rock mass is achieved while reducing the seismic impacts of blasting.
