| 摘 要： | 通过对元山子矿区水文地质特征的分析,矿区有四个含水层,三个隔水层,按照水文地质单元构成要素,结合地表分水岭情况,可将矿区划分为三个水文地质单元,认为该矿区水文地质条件总体比较简单,地表水对矿床充水作用较小,并对矿坑涌水量进行了预测计算,地表水汇入量预测采用地表径流模数法计算,地下水涌入量采用狭长水平坑道法,综合矿坑地下水及地表水涌入量数据,求得矿坑(Ⅰ南/Ⅰ北、Ⅱ、Ⅲ)一般涌水量为846.2m^3/d和732.4m^3/d,最大涌水量为36118m^3/d和27080.1m^3/d,为以后矿山开采提出了建议。

| Abstract: | The Yuanshanzi Ilmenite Mine Field may be divided into three hydrogeological units,containing 4 aquifers and 3 confining layers.In general,its hydrogeological condition is relatively simple.The amount of mine water gushing is predicted and calculated.The surface runoff modulus method is used to predict the inflow of surface water.The groundwater inflow is calculated by the narrow and long horizontal tunnel method.Integrated groundwater and surface water inflow data indicate that general water yields of mines Ⅰ(south)and Ⅰ(north),Ⅱ,Ⅲ are 846.2m^3/d and 732.4m^3/d,and maximum water yields are 36118m^3/d and 27080.1m^3/d,respectively. |
