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 explosives mixed mode was analyzed to examine the effects of rock powder particles on the physical properties and initiation behaviors of explosives. Test results show that the density of rock powder particle and the mass fractions of rock powder increase when mixed into explosives at constant density, that will bring significant influence to the performance of the explosives. It provides a reference for the improvement of the onsite mixed emulsion explosives clogging.
