strip mining, like other types of surface mining, finishes in hurting the area around the mine. the rock, gravel, trees, plants, and filth are dumped in regions round the mine. when it rains, this runs over the land and into watercourse and rivers. the rain pushes the mine filth on top of the region topsoil and buries it.mar 12, 2017 strip mining also uses significant amount of water to suppress dust. overall, the impact of coal mining in general on water is worth noting: it is not just the water used and depleted during the extraction process, but also the amount of water needed for converting coal into energy.may 14, 2018 strip mining is used for mining phosphate fertilizer in florida, north carolina, and idaho, and for obtaining gypsum in western states. however, the most common association of strip mining is with coal the examples of decimated land in appalachia have motivated calls for prevention, or at least major efforts at reclamation.the statistics of strip mine abuse numb the mind and overwhelm the spirit.
