Abstract
Abstract: A study of the different mechanisms which govern the evolution of particulate pollution in the atmosphere of a gallery of a uranium mine (deposition on the walls, coagulation) is presented.As a first step, the numerical coefficients which characterize the aerosol are determined from the air flow and the surface state of the walls. From these results a theoretical model is constructed and applied to a simplified type of mine gallery, a cylindrical duct with turbulent air flow. The results obtained with this model are compared with experimental values.In the second step, these results help to forecast the evolution of particulate pollution for different conditions of the mining environment. This work gives some ideas for research on methods of decreasing the particle concentration and the radioactive aerosol in the air of a uranium mine.
