摘要
喀斯特渗漏是在碳酸盐岩分布区修建尾矿库常遇到且必须解决的重大问题。在云南普朗铜矿尾矿库地下水示踪试验工程实例中,通过对比使用染料示踪法与化学离子示踪法表明,化学离子示踪法更适用于碳酸盐岩分布区。由时间-浓度曲线及实验结果确定了拟建尾矿库地下水运移方向、地下水流速,评价了地下喀斯特发育状况,为拟建尾矿库的防渗设计提供依据。
The karst leakage is the most important question to be encountered and necessarily solved to build the tailing reservoir in the karst area. In the groundwater tracing test for the tailing reservoir in the Pulang copper deposit, the chemistry ion tracing test method is appropriate in the carbonate distribution area by contrast to the dye tracing test method. By concentration-time curve and test result, the direction of groundwater move and flows of groundwater in the tailing reservoir is determined and the hydrogeological conditions in karst area are evaluated. This provides reliable evidences for the design of preventing leaking in the tailing reservoir.
