垂直水平联合自流排渗在银山矿业尾矿库降渗工程中的应用

为解决江西铜业集团银山矿业尾矿库安全检查中发现的坝体浸润线超高问题，保证坝体稳定性，结合尾矿库现场实际情况，在充分分析不同排渗方式特点的基础上，提出采用垂直水平联合自流排渗方式，并制定了经济合理可行的技术方案。通过浸润线观测数据表明:在落实排渗方案以后，坝体浸润线有明显的下降，坝体局部渗水、沼泽化现象有明显改观，有效地保证了坝体稳定性。

Application of Vertical Horizontal Combined Gravity Drainage in Seepage Reduction Engineering

In order to solve the problem of super high saturation line of the dam body obtained from the investigation of potential safety hazards of Yinshan mining tailings pond of Jiangxi Copper Group,and to ensure the stability of the dam body,combined with the actual situation of the tailings pond site,on the basis of fully analyzing the characteristics of different drainage methods,the vertical horizontal combined self flow drainage method is proposed,and an economic,reasonable and feasible technical scheme is formulated.Through the observation data table of saturation line It is clear that after the implementation of the drainage scheme,the saturation line of the dam body has obviously decreased,and the local seepage and swamping of the dam body have significantly improved,effectively ensuring the stability of the dam body.
