发布时间：2018-08-09 12:39
【摘要】：本文采用自行设计的氡析出实验装置,开展了不同功率超声作用下的饱和水介质氡析出实验,研究铀矿石破裂前超声声发射与岩石氡异常规律。实验结果显示:超声作用对氡析出有明显影响,且随着超声功率的增加而增大,呈线性趋势。但随着实验时间的推移,氡析出逐渐恢复实验初始水平,超声作用结束30 min后,饱和水试块的氡析出能力相对初始时并没有显著的变化。实验结论为铀矿开采过程中氡的防护提供了理论依据。
[Abstract]:In this paper, a self-designed experimental device for radon exhalation is used to study the ultrasonic acoustic emission and rock radon anomaly in saturated water medium under different ultrasonic power. The experimental results show that the effect of ultrasound on radon emission is obvious, and increases with the increase of ultrasonic power, showing a linear trend. However, with the passage of experimental time, the radon exhalation gradually restored to the experimental initial level. After 30 min of ultrasonic action, the radon exhalation capacity of saturated water samples did not change significantly. The experimental results provide a theoretical basis for the protection of radon during uranium mining.
