Introduction. The main objective of blasting in mines is to break in-situ rock mass to smaller rock fragments. More specifically, the goal is to achieve a specific fragment size distribution that eases handling, while minimizing damage to the final pit wall. 1 Fragmentation can affect the productivity and efficiency of downstream operations including digging, crushing, and grinding.

In the mining industry blasts are usually designed to fracture the in-situ rock mass and prepare it for excavation and subsequent transport. The run of mine (ROM) fragmentation is considered good when it is fine enough and loose enough to ensure efficient digging and loading operations. Mining optimisation strategy is hence usually focussed on minimising total mining costs and maintaining ...
