Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of generating air bubbles, to gain fundamental understanding of the foaming mechanism in currently used gassing techniques, and to invent ways to stabilise large bubbles within the emulsion. The project will provide scientific underpinning for the development of a new range of emulsion explosives manufactured by Orica for Australian and international markets, maintaining the Orica's position as a leader in the field of emulsion explosives.

泡沫炸药乳化液的产气机理及稳定性。开采诸如煤之类的矿物涉及用乳化炸药破碎周围的岩层或矿石本身。决定乳化炸药对特定采矿作业的适用性的最重要的特性之一是其爆炸速度，其可以通过改变分布在乳化基质中的气泡的数量和大小来调节。本项目旨在开发产生气泡的新方法，对目前使用的充气技术中的发泡机制进行基本了解，并发明稳定乳液中大气泡的方法。该项目将为澳瑞卡为澳大利亚和国际市场生产的一系列新型乳化炸药的开发提供科学依据，保持澳瑞卡在乳化炸药领域的领导地位。
