| 摘 要： | 为了研究井下氡浓度分布情况,对复杂管网式地下铀矿井氡浓度进行了研究,建立了铀矿井的三维物理模型,并基于CFD软件对铀矿氡浓度进行数值模拟,得出了与实际情况较接近的氡浓度分布图。研究结果表明,在通风管入口附近氡浓度较小,掘进面附近的氡浓度较大。氡浓度在垂直方向上,高度与氡浓度成反比关系。

| Abstract: | In order to study the concentration distribution of underground uranium,the three-dimensional physical model of uranium mine was established,and the uranium ore concentration was numerically simulated based on CFD software.The results show that the concentration of radon near the entrance of the ventilation pipe is small,and the concentration of radon near the excavation face is large.The radon concentration is in the vertical direction,and the height is inversely proportional to the radon concentration. |
