要知道气泡敏化的散装乳化炸药在炮孔中的密度不是直观。装药密度是影响炸药性能的关键参数之一。因此,为准确预测炸药的爆破效果以确保有效地使用这些产品,对气泡敏化的散装产品在炮孔中的特性进行监测很重要。叙述了气泡敏化的乳化炸药的炮孔密度、密度梯度、装药连续性的现场监测技术,该项技术包括炮孔温度、压力的测量以及所选炮孔爆轰速度的测定。研究发现,炮泥对炮孔中炸药的压力没有产生明显影响;研究还显示炮孔组拱在装药后几小时显著地影响着炮孔压力;研究观测了不同产品沿装药的炮孔密度梯度与爆速的相互关系。
To know the density of bubble-sensitized bulk emulsion explosives in the hole is not intuitive. Charge density is one of the key parameters that affect the performance of explosives. Therefore, in order to accurately predict the blasting effect of explosives to ensure the efficient use of these products, it is important to monitor the characteristics of the bubble-sensitized bulk product in the borehole. The field monitoring technique of blasting density, density gradient and charge continuity of bubble sensitized emulsion explosives is described. The technique includes the measurement of blasthole temperature and pressure and the determination of the detonation velocity of the selected blasthole. The study also found that shotcrete had no significant effect on the pressure of explosives in the blast hole. The study also showed that the blasting of the blasthole group significantly affected the blast pressure at several hours after charging. The blasting density Correlation between gradient and detonation velocity.
