What is Blasting Impact on Downstream Costs about?

This document reviews 9 studies on the relationship between blasting and downstream costs. Several key findings are summarized: 1) Increasing the powder factor from 0.58 to 0.66 kg/m3 resulted in a 12% reduction in electrical consumption for grinding at a gold mine. 2) Increasing the blast effort for limestone by increasing charge length and decreasing burden/spacing achieved overall savings of 10% and 7% respectively for mining and processing. 3) Testing on 7 rock types found that blasting reduced th
