This project aims to develop a new class of emulsion explosives, which are not susceptible to hot and reactive rock conditions in very deep-level ore mines. These emulsions will contain a tuneable polymer network to prevent collapsing of the emulsion columns in hot upholes in high temperature mines, along with additives to eliminate the exothermic reaction with the rocks. If not prevented the reaction can cause premature detonation or deflagration of the emulsion causing fatal injuries and generation of toxic NOx gases. Increase in economically and safely extractable deep-level ore volume that generates greater export earnings and more jobs are expected project outcomes, as is reduced atmospheric pollution.

该项目旨在开发一种新型乳化炸药，该炸药不易受到深部矿井中热和反应性岩石条件的影响。这些乳液将含有可调节的聚合物网络，以防止高温矿山热井中乳液柱的塌陷，以及消除与岩石的放热反应的添加剂。如果不加以阻止，该反应可能会导致乳液过早爆炸或爆燃，从而造成致命伤害并产生有毒氮氧化物气体。项目的预期成果是增加经济、安全地开采的深层矿石量，从而产生更多的出口收入和更多的就业机会，同时减少大气污染。
