Gassing Mechanism and Stability of Foamed Explosive Emulsions

泡沫爆炸乳剂的产气机理及稳定性。开采诸如煤之类的矿物需要用乳化炸药粉碎周围岩层或矿石本身。决定乳化炸药是否适合特定采矿作业的最重要的性质之一是它的爆轰速度，这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。目前的项目旨在开发产生气泡的新方法，对目前使用的气体技术中的起泡机制有基本的了解，并发明稳定乳液内大气泡的方法。该项目将为Orica为澳大利亚和国际市场生产的新型乳化炸药的开发提供科学基础，保持Orica在乳化炸药领域的领先地位。

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.
