摘要:
目的 探讨原地浸出矿氡污染的规律及相应的防护措施。方法 对工作现场进行工艺分析、氡浓度连续监测,根据监测结果提出整改措施并进一步验证其效果。结果 试运行整改前氡浓度监测结果显示,本项目氡浓度偏高的场所集中在浸出液处理厂房的低跨车间,连续两次整改后,各个工作场所的氡浓度均满足国家相关标准的要求。结论 导致浸出液处理厂房低跨车间氡浓度超标的主要原因是对原地浸出采铀工艺过程中的氡析出认识不足,提示工程设计和施工中一定要密闭氡源,防止其析出扩散至厂房等工作场所。
Abstract:
Objective To explore the regularity of radon pollution with in-situ leaching mine and appropriate protective measures.Methods The radon contamination situation was analyzed and the radon concentration was monitored,and then based on the monitoring result corrective measures were proposed to further verify its effect.Results The monitoring results of radon concentration before rectification showed that high concentration of radon concentrated in the leaching solution processing workshop,the radon concentration met the requirements of the relevant national standards after twice rectification.Conclusions The main reason of high concentration of radon in the leaching solution processing workshop is lack of knowledge of radon concentration in the in-situ leaching of uranium mine.It prompts that the radon source should be completely airtight to prevent radon spreading to factories and other workplaces.
