纳米技术在矿用炸药中的应用可能性研究(英文)

Study on the Improvement of Mining Explosives by Nanotechnology

从爆轰理论的基本方程分析了二维爆轰中随径向距离变化的压力对能量分配的影响。并在此基础上,对含铝矿用硝胺乳化炸药中的铝粉反应过程进行了理论分析,认为铝粉的吸热和放热反应过程对总能量分配为冲击波能(用于支持爆轰波以及破坏岩层)以及抛掷能(用于抛掷)的比例影响明显。由于该过程取决于铝粒子包覆材料的热性能,如热传导、比热等,故可通过纳米技术影响或改变包覆铝粒子氧化材料的性质、控制包覆材料的熔化,以及选择其热性能,以最优比例分配使用总能量,达到最佳的爆破效果。

Nanotechnology techniques may be used to influence,or establish,certain properties of materials such as the oxide coating on aluminum particles. It is shown how control of the melting of the coating on aluminum particles in a mining explosive helps control the split of the total energy released into shock energy,that supports the detonating shock wave and heave energy,that heaves the overburden off the ore body. By appropriately choosing the thermal characteristics of the coating on the aluminum particles the total energy may be split into the most advantageous proportions.
