南京市矿山尾矿利用现状及加快尾矿利用的对策

随着矿业开发规模的加大，大量尾矿的露天堆存，不仅造成了资源的浪费，对环境和人类的危害也日益严重。尾矿利用是充分利用资源和消除尾矿对环境的危害的重要途径，对此 有充分认识，南京尾矿库存总量约２５００万ｔ，每年新增尾矿量５０万ｔ，尾矿的利用程度和范围还远远不够，就加快南京市尾矿利用步伐提出了对策。

Current Situation of Tailings Development and Main Measures to Speed Up Tailings Utilization in Nanjing

With the expansion of mining industry in Nanjing,Jiangsu Province,large amount of tailings from existing mining sector is collected and stacked out door,which has resulted in not only the waste of mineral resources,but also the significant impact on the environment of human survive.Utilization of tailings is an important way to make full use of resources and remove harmful impact on environment.It is essential to make full understanding on this point.The tailings in Nanjing City is about 25 million tones with an annual increasing of 0 5 million tones Now,the utilization is far from enough in degree and scope.The paper puts forward several countermeasures to deal with the tailings,such as comprehensive research on the utilization of tailings,making preferential policy for tailings development,setting up group of model engineerings and mines,legal and regular restriction,experiment and research of ecological recovery of mines
