矿业环境影响的地球化学研究

GEOCHEMISTRY IN THE MINING ENVIRONMENTAL IMPACT

矿业开发对周围地区带来巨大的环境影响。矿山废弃矿石和脉石堆、矿山选矿废石、尾矿、冶炼熔渣、矿山酸性排水、土壤重金属元素、河流及其沉积物中的重金属、大气污染等都极大地影响了矿山地球化学环境和生态系统。甚至在矿山工业关闭后 ,长期的环境影响依然是一个重要的地球化学研究内容。环境方面的地球化学化学扰动和平衡 。

Mining activities bring about giant environmental impacts on the affected areas. Mining wastes, including wasted ore and gangue piles, mill waster, tailing dump, slags, acid mine drainage, heavy metals in the soils, river,stream water and sediments, and the air pollution have greatly disturbed the geological environment and the ecological system in the mining area. Even after the closing of the mining industry, the long term environmental effect is still a geochemical problem.Great attention should be paied to the study of geochemical disturbance and balance of the mining environment.
