critical to evaluating the impact of blasting on the entire Thabazimbi mining operation. Waste mining constitutes the major part of the operation with a stripping ratio of around 10:1, and as such is a key area to improving efficiencies. This research focuses only on the waste mining component with ore mining to be considered at a later date.
