Ammonium Nitrate Fuel Oil, commonly known as ANFO, or ANFEX (a trade name registered by AECI), in mining industry jargon, is an excellent explosive charge for large scale blasting as it combines both performance and low cost. It is used mainly in dry holes, but can be used in wet-holes, provided it is properly packed in special water-proof packages before being inserted into the blast holes. ANFO performs well in large diameter holes in both hard and soft rock provided that it is well charged and properly confined. The density p of ammonium nitrate is a very important parameter as it greatly influences the effectiveness and the overall performance characteristics of the mixture. It is considered to be the technical parameter to be controlled by the manufacturer so as to obtain the optimum efficiency of the product. The conventional density of ANFEX produced by AECI is 0,76 g/cc. The need to develop a lower energy explosive for stoping has prompted the production of the low density ANFEX (LDA) at a density of 0,67 g/cc. In France, the Grande Paroisse Company has succeeded in lowering the density to 0,64 g/cc.
