This paper is a case study showing the assembly of available rock property parameters for the purpose of blast design. Blast optimization now includes subsequent milling and requires a full knowledge of the rock mass. Individual blast holes should be designed using all available data. The parameters include: geologic layer from diamond drilling, shovel performance, crushing plant experience from that area, drill monitoring, magnetic susceptibility from a downhole probe, size analysis history from digital image analysis, compressive strength tests of problem areas and cross hole sonic testing. Bedding thickness observed from drill core appear to have a strong influence on fragmentation.
