WMAN Environmental Impacts of Mining. Hundreds of tons of rock are unearthed, moved, and crushed in mining operations significantly increasing the amount of dust and particulates in the air. In addition, mine tailings, which may contain finely ground and even toxic waste, can become airborne.May 10, 2017 Predicting mine waste environmental impacts before it’s too late. Mining for precious, base and ferrous metals can result in millions of tonnes of tailings and waste rock, which if left unmanaged can have dire environmental consequences. Poorly designed storage facilities can potentially leak pollution for centuries or even millennia.Surface mining or open-pit mining depends on the removal of all surface soil and rock covering the desired Uranium. While it is safer for the miners than underground mines since they are not exposed to roof-falls or pneumoconiosis, it blasts 30 times topsoil than Uranium ore and the resulting land is left with radioactive, toxic elements.
