  • 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
