一、酸性矿坑水的危害我国硫铁矿、煤矿和多金属硫化矿存在酸性矿坑水,在开拓的矿山中占有相当的数量。这些矿山由于矿石中含有一定数量的硫化物,经氧化后往往形成酸性矿坑水。这种水在井下腐蚀管道和设备,危害工人身体健康;排出井巷,污染环境和水源,严重地影响着工农业和渔业生产,给矿山带来的经 First, the harm of acid mine water China’s pyrite, coal mine and polymetallic sulfide ore acidic pit water, occupy a considerable number of open mines. Due to the ore contains a certain amount of sulfide, these mines often form acidic pit water after oxidation. Such water corrodes pipelines and equipment in the mine and endangers the health of workers. Exhausting shafts and alleys, polluting the environment and water sources, have a serious impact on industrial, agricultural and fishery production,
