In East Germany, uranium mining and milling by the Soviet-German Wismut Company lasted from 1946 to 1990. The Wismut uranium mining area consists of numerous waste rock dumps (WRDs) in Saxony and Thuringia. The waste rock is classified as radioactive and it is partially susceptible to acid rockDESIGN OF WASTE DUMPS WITH FLOW-THROUGH ROCK DRAINS,Design of flow-through waste dump drains requires an assessment of the peak flows which the drain must carry. Normally, basic hydrologie parameters are developed as part of the water management plan for a mining development, so that they need only be applied to the specific catchment upstream of the waste dump. The recommended design flow for flow-through waste dumps is the 200-year return,6 Potential Environmental Effects of Uranium Mining,,The disposal of waste rock is an issue in mining in general, because the volume of the mine voids cannot contain the entire volume of material removed during a mining operation; waste rock is typically stored in aboveground piles near a mine to minimize handling and disposal costs. Management of waste rock piles at uranium mines has evolved from the realization that all waste rock does not,
