I am working on a project related to Mine to Mill optimisation. I would like to predict and incorporate the heterogeneity of fragmentation in the associated analyses. The question, however, is that how we can incorporate the three-dimensionality of the problem in fragmentation prediction? Is there any approach available to predict the gradation of the rock fragment size distribution due to energy partitioning, the network of natural fractures, and stemming effects? Any idea is highly welcome.
Dear Salmi, this work from Professors Ouchterlony and Sanchidrián will probably help you, as it review the history of rock fragmentation prediction models. Hope it helps.
All the best.

Thanks Jorge, I have already been using those approaches (the Fragmentation Energy-Fan, and the Distribution Free models). But I am looking for a three-dimensional (3D) prediction of rock fragmentation.
Dear Salmi, did you try to check if the Multiple Blasthole Fragmentation (MBF) model developed by Ruilin Yang fits to your needs? it is a 3D approach model based on the near-field vibration modeling, where several of the major blast and rock parameters can be addressed (hole and bench 3d geometries, vod and seismic velocities, etc.). He has published several papers about his model:

You can find others of his papers in FRAGBLAST and ISEE proceedings as well.
