非闭库尾矿安全回采工程实践研究

Study on engineering practice of safely mining non-closed tailings

目前,矿产资源日渐枯竭,尾矿回采极具重要意义。以某非闭库尾矿回采为例,重点介绍了尾矿回采方案并计算了回采过程中尾矿库正常运行期、洪水运行期以及特殊运行期的安全系数。针对其计算结果,提出了回采安全的技术措施,为尾矿安全回采提供了工程实践依据。

Upon the depletion of resources, tailings recovery is a matter of great importance. The paper takes safety mining of non-closed tailings practice for example, focuses on the tailings recovery plan and calculates the safety factors of normal operation of the mining process ,the flood operation and special operation periods. Based on the results, it puts forward technical measures for safety mining to provide an engineering practice basis for safely mining tailings.
