尾矿库细粒尾矿入库防洪安全研究

Study on Flood Control Safety of Stacking Fine-grained Tailings in Tailings Storage Facility

针对尾矿井下充填后溢流部分入库使尾矿库防洪压力偏大的问题,以某金矿尾矿库为研究对象,提出了强化其防洪能力的安全措施。结果表明:采取逆向支管水力冲击放矿方式,控制库水位和干滩,能显著地提高尾矿库的干滩长度、干滩坡度及安全超高,并极大地提高了尾矿库的防洪安全能力。

To address the problem of excessive flood control pressure of the tailings storage facility caused by the overflow part of the tailings entering the tailings storage facility after underground filling is finished,a tailings storage facility of a gold mine is taken as the research object,and safety measures to strengthen its flood control capacity are put forward.The results show that adopting the reverse branch hydraulic impact ore-drawing method to control the water level and dry beach of the tailings storage facility can significantly improve the length,slope,and safety superelevation of the dry beach,and greatly improve the flood control safety capacity of the tailings storage facility.
