| Abstract |
Experimental and theoretical studies were carried out on prilled and pulverised ammonium nitrate-fuel oil (ANFO) mixtures to quantify the effects of stoichiometric composition, non-ideal detonation behaviour, and expansion volume on production of carbon monoxide and nitrogen oxide fumes. Results included: (a) the nitrogen oxide fume amounts agreed with those from standard Crawshaw-Jones results; (b) the theoretical calculations based on an equilibrium detonation code (called TIGER) predicted production of toxic fumes; (c) post-detonation oxidation of carbon monoxide causes difficulties for extrapolation of laboratory measurements to mine conditions; (d) the detonation velocity decay rate is a useful experimental parameter for correlating toxic fumes production with non-ideal detonation behaviour. |
