[en] By application of groundwater modeling software, quantitative analysis of in-situ leaching uranium flow field for seepage-dispersion field is carried out. Seepage field is divided into several feature region. Horizontal-vertical characteristic parameters of seepage field, dilution rate of flow field and rate of injection contribution are defined According to dilution rate change, flow filed is divided into several periods. Based on the stratum homogeneousness, drawing and injecting flow rate, well spacing, filter installation site as well as its length etc. influence factors, the modeling of hydrodynamic force and solution seepage-dispersion field at one in-situ leaching uranium field in the Inner Mongolia is established. Therefore, quantitative comparison is conducted by those parameters at the flow field. (authors)
