| 摘 要： | 通常认为砂岩型铀矿含矿层的渗透性是地浸开采技术是否可行的重要条件。因此，研究地浸采铀的可行性和提高砂岩型铀矿含矿层渗透性成为重点。系统探讨了影响砂岩型铀矿含矿层渗透性的主要因素，即：碳酸盐、黏土矿物、夹层、隔层、地下水矿化度等。这为进一步研究砂岩渗透性提供了依据，同时对地浸采铀的浸出率和资源回收率也有着重要的理论意义和实际价值。

| Abstract: | The permeability of ore-bearing layer in sandstone-type uranium deposit is considered as the decisive condition whether the in-situ leaching technology for uranium deposit is feasible or not. It is quite significant to study the feasibility of in-situ leaching for uranium deposit so as to improve the permeability of the sandstone-type uranium deposit. The paper systematically summarizes that the major factors influencing the permeability of ore-bearing layer, i.e. carbonate, clay minerals, impermeable bed, intercalated bed, grade of salinity of the groundwater. The results provide a theoretical basis for the further study on improving the permeability of sandstone. This is theoretically significant and practically valuable to improve the leaching rate of uranium and the recovery of resources. |
