<p>The invention relates to the development of a low-density granular oxidising agent (PAN), the ingredients of which do not separate and are conferred with explosive properties through the simple mixture thereof with combustible ingredients, thereby producing a low-density granular blasting agent (PANFO). PANFO has many applications in the mining industry, in both open-pit and underground operations, said agent being suitable for use alone in applications intended to control damage to the banks or mixed with other explosives typically used in the industry. According to the invention, the density of the mixture can be adjusted to the conditions of the rock to be blasted and, consequently, the fragmentation requirements can be maximised. When used as a diluent of standard ANFO prill, the low-density reactive nature of PANFO eliminates the risks of detonation failures, associated with the segregation of the ingredients of the mixture, regardless of the desired degree of dilution or the level of segregation produced during pit loading.</p> |
