The case of AMYNDAION MINES
The particular work addressed the problem of atmospheric dispersion of particulate matter (PM) from the overburden dumps of a mine, using a commercial CFD software, includingmost of the complex physical phenomena in atmospheric diffusion. In the vicinity of the city of Amyndaion there is a large mine that provides lignite for the thermal power stations of the Hellenic Public Power Corporation. The excavated land is dumped in nearby open pits, which are planned to be extended Southern. These pits are sources of air-suspended particulate matter that can affect the nearby residential areas.
A numerical model was employed to simulate the present and future state of the overburden dumps. The results for various dispersion scenarios were compared with the estimations of empirical models, recommended by U.S. Environmental Protection Agency (EPA). The calculated results confirmed the increased impact to health if the dump site moves Southern.
