地下涌水时矿坑浸出液产量的计算

The Calculation of Leaching Liquid Output as Considering Underground Gushing Water

在地下涌水情况下浸出液的产量可以分为地下水位线以上和地下水位线以下两部分考虑。地下水位线以上部分可以用无地下涌水情况下浸出液经验计算公式计算,地下水位线以下部分可以用裘布依公式计算。以上述两个公式为基础,考虑地下涌水情况下,浸出液涌出后所剩余的地下含水要向下渗透对地下水位的影响,得出地下涌水情况下浸出液产生数量的计算公式,为深旧矿坑的填埋处埋提供了一定的理论依据。

The leaching liquid output when underground gushing water as considered is divided into two parts, that is below the underground water level and above the underground water level. The part which is above the underground water level is calculated using the empirical formula, while the part which is below the underground water level is calculated using the Dupuit＇s equation. The authors can obtain the formula which is used to estimate the output of the leaching liquor when the underground gushing water is considered, based on the above 2 formulas and considered the impact that the residual underground water after the leaching liquor having gushed will have a downward infiltration. It provides certain academic basis for treatment of landfill in deep and old mine.
