In this last presentation different ways of changing Drill-and-Blast design and how Drill-and-Blast is implemented to effect changes in Rom distribution are explored. Video footage of real blasts are used to illustrate this. The presentation culminates in a detailed examination of a published case history where a successful Mine-to-Mill blast was implemented. The resulting dramatic increase in SAG mill throughput and reduction in overall specific energy is discussed.

About this series

This is a 3-part series of presentations for Minerals Processors to provide an introduction to the understanding of, and tools necessary to conduct Mine-to-Mill programmes from a blasting and comminution perspective. Its aim is to provide the basics for Minerals Processors to help them achieve a successful outcome.

The 3 parts are entitled:

  1. The influence of feed size on AG/SAG milling
  2. An introduction to blasting
  3. Changing AG/SAG feed size through blasting

As far as possible use is made of data and information from published papers.
