Abstract
The quality of inlet air in shaft station is influenced by many factors,mainly including radon concentration of inlet air,radon emanation of palisades and uranium mine ore piles loaded in mine-cars.In this paper,an underground uranium mine in eastern China was selected as the research object;mathematical model for shaft station radon concentrations was then set up on the basis of the theories of decay in radioactivity and mass transfer in turbulent flow as well as continuity equation.Moreover,radon concentration of inlet air,number of awaiting mine-cars and radon exhalation rate of uranium ore piles loaded in the mine-cars were considered as variable factors,which were further used in sensitivity analysis with respect to the maximum shaft station radon concentration.Meanwhile,to explore which of those factors makes the most significant effect on shaft station radon concentration,five times of field survey were carried out and the sensitivities of each factor were analyzed.The results show that,with the existing conditions,the sensitivities of each influencing factor exhibit as radon concentration of inlet air is higher than the number of awaiting mine-cars while the latter is equal to the radon exhalation rate of uranium ore piles.关键词
