Using Low Density Explosives In Iron Ore Applications
pattern – ground mismatch – when the ground is easier to blast. As low density explosives produce less shock energy, there is less damage to final walls when utilized in trim blasts. Blasting efficiency is enhanced through a reduction in total quantity of explosive energy required to move less competent rock masses.
H BLASTING IN SURFACE EXCAVATION - Mining and Blasting
A new iron ore deposit is to be worked by surface mining methods with 15 m benches using 150 mm diameter blastholes. Since the prevailing condition is dry rock, it has been decided to use bulk ANFO with emulsion cartridges as primer. Assume that the overall density of compacted ANFO and the primer as 0.85 g/cm3 and the powder factor of 0.6 kg/m3.
