铀矿开采过程中氡不断地从矿岩裂隙、含氡矿井水、以及采空区和废弃巷道中析出.氡是铀矿开采中的主要有害因素。因此,铀矿井的通风不仅要为井下工人提供新鲜空气,创造舒适的工作条件,而且也是排氡的重要措施。在开采过程中,采掘工作不断扩大,采空区和废弃巷道越来越多,通风降氡的效果
Radon is continuously precipitated from ore rock fissures, radon-containing mine water, and mined-out areas and abandoned roadways during uranium mining.Radon is a major detrimental factor in uranium mining. Therefore, the ventilation of uranium mines should not only provide fresh air for underground workers, create comfortable working conditions, but also be an important measure for radon emission. In the mining process, mining work continues to expand, mined-out area and abandoned more and more tunnels, ventilation and radon reduction effect
