尾矿库和排土场都是高势能的泥石流重大危险源，二者的降雨入渗特性均较复杂。而当高等级排土场位于大型尾矿库的下游时，其复杂性更不言而喻。通过对太和铁矿的工程实例分析，计算得到尾矿库在千年一遇洪水条件下的浸润线分布，将其导入到排土场中作为初始条件，计算得到初始浸润线；再据此分析整个研究区域的降雨条件下入渗特性。研究结果表明，尾矿库内的浸润线分布对下游排土场的影响很大，入渗作用改变了排土场边坡内的地下水渗流场，而地下水的升高则是一个缓慢的过程。

Both of tailing pond and waster dump is high -potential fatal danger fountainhead for debris flow , and the infiltration characteristic are all complex of them .Especially , when a high-class dump is downstream of a large-scale tailing pond , the degree of complexity is more self -evident .Based on the engineering instance a-nalysis of Taihe Iron Mining , phreatic line under the case of the millennium of the tailing pond was obtained , which is introduced into the waster dump model as an initial condition to calculate the initial phreatic line .On the basis, the infiltration characteristic in the entire area under rainfall was analyzed .The study results showed that the phreatic line distribution in the tailing pond has great influence on the waster dump at downstream , the groundwater seepage field in the dump was changed by the infiltration , and the rise of groundwater is a slow .
