Velocity of detonation of AN base blasting agent with addition of hay and recycled rubber

摘要

Commercial Explosives are most often mixtures of oxygen and fuel components and supplements. ANFO explosives and emulsion explosives due to satisfactory detonation properties make the bulk of explosive consumption for blasting in mining industry and open pit excavation in the construction industry. Given the non-explosive properties of the ingredients, they have an advantage over explosive sensitized with nitro-derivatives or monomolecular explosive from the safety point of view. Requirements for the commercial explosives, especially blasting in populated areas, may be contradictory in the sense of the need to create sufficient pressure or mechanical work to fragment the rock, with minimal damage to the surrounding rock, outside the blasting zone and other minimum environmental impacts. By adding organic materials other than conventional explosive components, certain detonation properties may be amplified or reduced, or available energy can be concentrated or impaired in surrounding rock. By using organic waste materials, the detonation properties of the AN mixtures can be adjusted with a satisfactory blasting effect, and the additional benefit of disposal or exploitation of such materials. The paper presents the results of velocity of detonation measurements for the AN mixtures with recycled rubber and hay. in different ratios.
