Sažetak
ANFO is the most common explosive for civil use in the fields of mining and civil engineering. Satisfactory blasting performance, relatively low price, safety during blasting operations, a simple manufacturing process and the possibility of mechanical loading of boreholes are the main reasons for its frequent use. It has certain disadvantages, it is not water resistant and it has a relatively low velocity of detonation. It is possible to improve the properties like density, velocity of detonation and water resistance by mixing ANFO with emulsion matrix in certain proportions. This paper presents in situ measurement of detonation velocity of ANFO and ANFO explosives with certain proportion of emulsion matrix (heavy ANFO blends). Based on the measurement results, the dependence of the velocity of detonation on the percentage of added emulsion matrix was established.
