摘要
本文介绍了在铀矿开采过程中氡及其子体在介质中的渗流的必要条件 氡源、通道、压力剃度 ,对氡及其子体在介质中的渗流规律进行了详细的研究。基于该研究成果 ,提出了合理的调整地下通风网络的方案 ,控制氡的扩散、渗流 ,确保铀矿山地下开采场地及地表环境不受污染。
The source of radon,the passage and the pressure gradient are the prerequisites for the formation of the permeation of radon and radiation products in the process of recovering underground uranium deposits.This paper conducts a detailed study on the regularities of the permeation.Based on the research results,it is suggested that the ventilation network should be adjusted in order to control the permeation and dispersion of radon and its radiation products and ensure the underground stopes and the surface are protected from being contaminated.
