1. A process for improved blast design including the steps of:
acquiring geological data about a blast site from multiple data sources;
extracting one or more blastability labels from the geological data;
mapping the blastability labels in two or three dimensions;
designing a pattern of blast holes based on the mapping;
designing explosive placement for each blast hole based on the blastability label for that blast hole;
loading each blast hole in the pattern of blast holes with the designed explosive for that blast hole; and
detonating the explosive,
further including smoothing the mapping of labels to simplify the grouping of blastability labels within blast holes and between blast holes.
