岩粉对混装乳化炸药性能影响的试验分析*
Experimental Analysis on the Performance of Mixed Emulsion Explosive Due to the Addition of Rock Powder
摘要:
针对矿山爆破工程中,采用现场混装乳化炸药进行装药,并进行岩粉直接堵塞炮孔,存在岩粉颗粒侵入炸药内部并与炸药相互混合的情况,对堵塞过程中岩粉侵入以及与炸药混合模式进行试验分析,研究岩粉颗粒对炸药的物理性能及起爆性能的影响。试验结果表明,不同的岩粉颗粒密度以及混入炸药内部岩粉质量分数不同,对炸药的影响程度也不同。具体表现为岩粉颗粒密度增大,对炸药的影响程度增大;而对于同一密度岩粉颗粒,随着混入炸药质量分数增大,对炸药影响也逐渐增大。为改善现场混装乳化炸药堵塞方式提供一定的参考依据。
Abstract:?
In mine blasting projects, onsite mixed emulsion explosives filling and direct blast hole clogging by rock powders are used , which may result in the rock powder particles intrusive into the explosives'internal structure and mixing with each other when charging with .To this ends , the rock powder intrusion during the clogging process as well as explo-sives mixed mode was analyzed to examine the effects of rock powder particles on the physical properties and initiation be -haviors of explosives .Test results show that the density of rock powder particle and the mass fractions of rock powder in -crease when mixed into explosives at constant density , that will bring significant influence to the performance of the explo-sives.It provides a reference for the improvement of the onsite mixed emulsion explosives clogging .
