In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization of drilling and blasting parameters. Rock fragmentation depends upon two groups of variables: rock mass properties which cannot be controlled and drill-and-blast design parameters that can be controlled and optimized.
