| 摘 要： | 为了研究围岩中温度对氡析出率的影响,选取某铀矿铀尾矿矿砂试样,根据相似准则设计并制作了测量多孔射气介质氡析出率的室内试验装置。采用RAD-7氡测量仪,运用等时间间隔取样方法测量氡浓度。采用对照试验的方法研究了温度对多孔射气介质氡析出率的影响规律。试验结果表明,在自然压力下,在温度为20℃到60℃范围内,随着温度的升高,多孔介质氡析出率逐渐增大,并且氡析出率与温度符合线性函数关系。

| Abstract: | In order to study the effect of high temperature on the radon exhalation rate of surrounding rock ,a uranium mine uranium tailing ore sample is selected ,according to the similarity criterion ,the porous medium emanation measurement of indoor radon exhalation rate test apparatus is designed and made .RAD - 7 radon measurement instrument is applied and the same time interval sampling methods are also used ,to measure radon concentration .The method of controlled trials is adopted to study the influencing rules of the temperature on the porous medium emanation of radon exhalation rate .Test re-sults show that under natural pressure ,the temperature ranged from 20 ℃ to 60 ℃ and with the increase of temperature , porous medium radon exhalation rate increases gradually ,and the radon exhalation rate and temperature conforms with the linear function relation . |
