Improvements and Safety Assessment of Uranium Mine Ventilation System

摘要：

Ventilation has been proved to be a main method, to eliminate radon and radon daughters of uranium mine. At present, in the uranium mine ventilation system, several problems are existed as follows: jumbled systems, serious air leakage, series ventilation, low effective air volume rate and unqualified rate of concentrations of radon and its daughters and so on. According to the practical rectifications of uranium mine ventilation system, some summarizing experiences of improving measures are presented in the paper, which include investigating radon source, controlling the direction and size of radon seepage, exerting the inhibition effects of ventilation, reducing air leak, increasing the ability of radon dilution and establishing complete ventilation system. In addition, a practical example is analyzed to introduce safety assessment method for uranium mine ventilation system.
