甘肃省尾矿库环境风险分析及防范措施

尾矿库是矿山巨大的环境风险源，严重威胁着周边生态环境和居民的生命安全。通过现场调研和资料收集，分析了甘肃省尾矿库的基本现状及环境风险特征，并提出环境风险防范措施。研究结果表明，甘肃省尾矿库主要分布在陇南地区，以山谷型、涉重尾矿库为主，小型库居多，安全度水平较低，存在一定的环境风险，威胁着周边水体、大气和土壤环境，选址、设计与施工、监测设施、生态恢复和环境应急体系是环境风险防范的重点工作。

Environmental Risk Analysis and Countermeasures of Tailings in Gansu Province

Tailings is a huge source of environmental risk for mine，which seriously threaten the surrounding ecological environment and the lives of residents.The basic situation and environmental risk characteristics of tailings in Gansu Province were analyzed through site investigation and data collection，and the environmental risk prevention measures were proposed.Results showed that tailings in Gansu Province mainly distributes in Longnan area with a low level of safety，mainly in form of valley type，heavy tailings reservoir and small-sized reservoir. There are certain environmental risks，which threaten the surrounding water bodies，soil and atmospheric environment.The site selection，design and construction，monitoring facilities，ecological restoration and environmental emergency system are key tasks for preventing environmental risk of tailings in Gansu Province.
