矿山企业对含水盆地的影响最严重,这是因为在采矿时通常都要降低水位,结果形成降落漏斗,它在许多情况下涉及含水层供水区域。另外,矿山的矿石加工厂和与之有关的尾矿场及其它构筑物可能成为地下水和地表水的污染源,其生产用水含有各种有害物质。工业场地的供水系统漏失和生产用水的排放量也可能成为地下水的附加污染源。 Mine enterprises have the worst impact on the water basins, as water levels are usually reduced during mining and as a result, they form landing funnels, which in many cases involve aquifer water supply areas. In addition, mine ore processing plants and their associated tailings and other structures may become sources of contamination of groundwater and surface water, and their production water contains various hazardous substances. The loss of water supply systems and the discharge of production water at industrial sites can also be an additional source of groundwater contamination.
