Abstract

ANFO eksplozivi se zbog svojih zadovoljavajućih minersko tehničkih i detonacijskih svojstava te relativno niske cijene najviše koriste za gospodarska miniranja u rudarstvu i graditeljstvu. Uz ekonomski čimbenik, sigurnost prilikom miniranja, jednostavnost proizvodnje na mjestu upotrebe i mogućnosti mehaniziranog punjenja bušotina dodatni su razlozi učestalosti upotrebe. Premda su minerska svojstva ANFO eksploziva dobro poznata, često se prilikom izvođenja miniranja ne vodi računa o uvjetima postizanja optimalnih detonacijskih parametara.
U radu su sistematizirani čimbenici koji utječu na brzinu detonacije ANFO (ANFO i Heavy ANFO) eksploziva te se daje pregled istraživanja u području ANFO eksploziva izvedenih posljednjih godina. Pored empirijskih podataka u radu se koriste i podaci dobiveni računalnim modeliranjem.

Abstract (english)

ANFO explosives are most comonly used explosives in mining and civil engineering due to their satisfactory technical and detonation properties as well as for their low price . Along with their low price, they are safe to use, they can be easily produced on site, also possibility of mechanized charging of boreholes are all reasons for their common usage. Though blasting properties of ANFO explosives are well known, often at blasting sites achieving of optimal detonation parameters is not taken into account.
In this papers factors which affect velocity of detonation of ANFO (ANFO and Heavy ANFO) explosives are systematized. Also it gives overview of research on ANFO explosives in recent years. Along with empiric data paper uses data obtained with detonation modelling.
