浙江庆元铅锌矿尾矿库销库与改建城市森林公园的实践

A Practice for Closing the Tailing Pond of Zhejiang Qingyuan Lead-zinc Mine and Transforming It into an Urban Forest Park

浙江庆元铅锌尾矿因富含铅、锌等重金属,给周边带来了较大的安全隐患和环境风险。为保证尾矿库安全、减少对周边环境的影响,详细介绍了在尾矿库销库,改建城市森林公园的实践中的“四横三纵两固一平一绿”措施,从而使尾矿库变成了森林公园,既解决了尾砂大量堆存带来的安全风险、环境风险、社会影响、土地占用等问题,又将当地城区向周边森林山体环境进行了拓展,促进了社会的和谐发展,这对类似重金属尾矿库处理开拓了思路,作出了示范。

The tailing pond in Zhejiang Qingyuan Lead-zinc Mine contains a large amount of heavy metals such as lead and zinc,which has brought great hidden safety hazards and environmental risks to the surrounding areas.In order to ensure the safety of the tailings pond and reduce the impact on the surrounding environment,the measures of"four horizontal,three vertical,two solid,one flat and one green"in practice of closing the tailing pond and urban forest park was introduced,which makes tailings pond into an urban forest park.It not only solves the safety risk,environmental risk,social impact,land occupation and other problems caused by the massive stockpiling of tailings,but also expands the local urban area to the surrounding forest mountain environment,promoting the harmonious development of society,which opens up ideas and sets an example for the treatment of similar heavy metal tailings ponds.
