The Mining function of a large mine was delivering sub-optimal fragmented rock from the Drill and Blast process, at just 90% passing 750mm.
To measure the location, quality and consistency of the holes drilled.
On a Process Behaviour Chart to understand whether the problem was systemic or not, as that determines how a problem is most effectively and efficiently addressed.
To remove them from the process and prevent their recurrence.
To ensure the changes were improvements, and were sustained.
Rock Fragmentation improved by almost 10%, with 98.8% of rock passing 750mm, generating over $12,000,000 per year in increased production!
