2. Theoretically well-founded settings with different distributions
3. Realistic scenarios using EKAs simulator and End User data.

Translation project 2 (A TP2): Muck pile fragmentation measurement techniques - from controlled samples to field trials (completed)

The aim of this research project is to assess the performance of the latest laser scanning technique for its application in qualifying the size distribution of muck-pile fragments for optimizing blasting parameters. It is expected that 3D laser scanning technique is faster and more reliable than other methods in evaluating the muck-pile fragmentation. To test this hypothesis, measurements using different methods will be conducted and analysed in a comparison study.
