Optimisation of blasting parameters to minimise on the fines generated.

Abstract

The main objective of the project was to optimize blasting to minimize the fine materials generated. The optimization of the blast an effort to eliminate excessively fine materials or to minimize the amount of big fragments in the ore stock pile. Nevertheless, to optimize the whole production system, it is better to use blasting layout that would produce the material fragmentation required by the remaining part of the production process. This has been used to evaluate blast design options and reduce the amount of trial blasting to produce the required blast fragment size.
