摘要
矿山尾矿由于产生大量酸性排水和释放重金属，污染地下水和地表水，破坏生态环境而成为人们关注的焦点。尾矿引起的环境问题是地表条件下，水－气－矿物复杂反应的综合结果。近年来尾矿矿物学的研究已经揭示出尾矿中矿物分解和形成的规律，水－气－矿物反应的机制和影响因素，酸性排水和重金属迁移规律，为尾矿环境危险性评价和尾矿污染防治提供了基础资料和新的思路。
Mine tailings give rise to acid drainage and heavy metals which pollute ground water, surface water and dest ecological environment. Environmental problem caused by mine tailings is the result of reactions among water, gas minerals under surface condition. Mineralogical study discloses the law of decomposition and formation of minerals, mechanism and factors of reactions among water, gas and minerals, the law of acid drainage and migration of he metals in mine tailings. Mineralogical study on mine tailings provides basic data and new idea for the evaluation endangered environment and prevention from the pollution of mine tailings.
