The performance of emulsion explosives used throughout the mining industry can be severely compromised by the effects of shear arising from pumping and detonation shock waves. Understanding how shear affects droplet coalescence and crystallisation is critical in differential energy blasting, where emulsion density and composition vary widely along the bore hole. This project aims to contribute to the understanding of the effects of shear, and develop new methods and additives to stabilise droplets and bubbles over a wide range of compositions and conditions. The goal of this project is to improve the efficiency and safety of rock-blasting operations, reduce environmental impact, and reduce operating costs, giving the Australian mining industry a competitive edge.

整个采矿业所使用的乳化炸药的性能会受到泵送和爆炸冲击波产生的剪切效应的严重损害。了解剪切力如何影响液滴聚结和结晶在差能爆破中至关重要，因为乳化液密度和成分沿钻孔沿着变化很大。该项目旨在促进对剪切效应的理解，并开发新的方法和添加剂，以稳定各种成分和条件下的液滴和气泡。该项目的目标是提高岩石爆破作业的效率和安全性，减少对环境的影响，降低运营成本，使澳大利亚采矿业具有竞争优势。
