Blast Fragmentation Analysis

The measurement and assessment of the size distribution of rock fragments produced by a blast event, used to evaluate blast performance and guide design optimisation. Fragmentation analysis methods include photographic image analysis using software tools, direct measurement, and sieve analysis of blasted muck. Target fragmentation ensures efficient loading by excavators, reduces crusher energy consumption, and avoids oversized rocks that require secondary breaking. In iron ore and gold mining, fragmentation analysis links blast design parameters to downstream processing performance and equipment utilisation.
