【摘要】:本文采用自行設(shè)計(jì)的氡析出實(shí)驗(yàn)裝置,開(kāi)展了不同功率超聲作用下的飽和水介質(zhì)氡析出實(shí)驗(yàn),研究鈾礦石破裂前超聲聲發(fā)射與巖石氡異常規(guī)律。實(shí)驗(yàn)結(jié)果顯示:超聲作用對(duì)氡析出有明顯影響,且隨著超聲功率的增加而增大,呈線性趨勢(shì)。但隨著實(shí)驗(yàn)時(shí)間的推移,氡析出逐漸恢復(fù)實(shí)驗(yàn)初始水平,超聲作用結(jié)束30 min后,飽和水試塊的氡析出能力相對(duì)初始時(shí)并沒(méi)有顯著的變化。實(shí)驗(yàn)結(jié)論為鈾礦開(kāi)采過(guò)程中氡的防護(hù)提供了理論依據(jù)。
[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.
