【摘要】 本文通过对矿区污染污物化学组分的分析，根据污染物渗滤液在含水层中的迁移规律，建立了污染物渗滤液在含水层中的迁移模型。针对在裂隙的一端具有分时注入源的单一裂隙的双重介质中的迁移规律，利用拉普拉斯变换法推导了解析解，以及简化条件下模型的解析解。为满足实际应用和确定模型中有关参数公式的需要，本文在解析解的基础上进行简化，得出了近似解析解及相应结论，对实验室利用近似解析解进行实验的条件的出了结论，推出了由近似解析解确定阻滞系数、固有扩散系数公式。针对矿区污染物对地下水污染的情况，作者提出了减少矿区污染物对地下水污染的建议。更多还原

【Abstract】 This thesis the compasition of mining area pollutant , according to the migration law of pollutant lerchate , this article establish the movement mathematics model of leachate in the water-beaaring stratum . As to the double medium movement model which has single crack , having the timesharing inject at one , this aarticle gives the analytical solution . Farthermore , it obtains the analytical solution of moder in the simplified condition .Filling the needs of practical use and the fixing of parameter and lormula , the analytical solution has also been simplified . Therefore the approximate analytical solution and relative conclusion are obtained . After debating the experiment conditions which utilice the analytical solution , this thesis derive the formula of the block and intrinsic diffusion coefficient obtained with analytical solution.Considerny the practically of groundwater pollution , the author givies some suggession about this problem .更多还原
