enviromental problems related to quarrying and mining

(PDF) The Environmental Impacts of Mining and Quarrying

As a result, enormous quantities of rock have to be excavated to obtain useful amounts of the mineral. In the long term, therefore, one of the main environmental concerns about mining and quarrying is the potential scar left on the landscape. Because open-pit mining involves the digging of vast pits or the removal of whole mountain tops, increasing pressure has been put on the mining industry to deal with waste heaps, mine and quarry
