Uneven and discontinuous calcareous sandstone and mudstone interlayers are distributed in the mining area of Bayin Qinggeli uranium mine. In order to explore the influence of low-permeability interlayers on uranium leaching effect, a three-dimensional unstructured grid lithology model of ore-bearing aquifer was constructed based on borehole data in the test mining area, and the flow field and solute transport process of in-situ leaching uranium under different extraction-injection methods were simulated. By introducing a matrix calculation method based on the actual extraction-injection flow of group wells, the solute mass ratio and natural groundwater content were quantitatively compared and analyzed. The results show that compared with the original extraction-injection method, after the extraction-injection methods of SYC-1 and SYZ-1 wells are interchanged, the range of groundwater drawdown funnel is reduced, the capture ability of pumping wells to leaching solution is significantly improved, the mass ratio of extracted and injected solute is increased by 1.7 times, the natural groundwater content in pumping volume is reduced by 29.4%, the hydraulic connection between extraction-injection wells is stronger, and the leaching effect is better than that of the original extraction-injection method. Calcareous sandstone and mudstone interlayers significantly hinder the hydraulic connection between extraction-injection wells, resulting in significantly different leaching effects of different extraction-injection methods.

巴音青格利铀矿采区内存在厚度不均且不连续分布的钙质砂岩和泥岩夹层,为探究低渗夹层对铀浸出效果的影响,基于试验采区钻孔数据构建了含矿含水层三维非结构化网格岩性模型,模拟了不同抽注方式的地浸采铀流场和溶质运移过程。通过引入基于群井实际抽注流量的矩阵化计算方法,定量化对比分析了溶质质量比和天然地下水含量。结果表明:相较于原始抽注方式,将SYC-1和SYZ-1井的抽注方式互换后,地下水降落漏斗范围减小,抽液井对浸出液的捕获能力显著提升,抽出与注入的溶质质量比提升1.7倍,抽液量中的天然地下水含量降低29.4%,抽注液井间的水力联系更强,浸出效果优于原始抽注方式;钙质砂岩和泥岩夹层显著阻碍了抽注液井间的水力联系,导致不同抽注方式产生显著差异化的浸出效果。

巴音青格利铀矿采区内存在厚度不均且不连续分布的钙质砂岩和泥岩夹层,为探究低渗夹层对铀浸出效果的影响,基于试验采区钻孔数据构建了含矿含水层三维非结构化网格岩性模型,模拟了不同抽注方式的地浸采铀流场和溶质运移过程。通过引入基于群井实际抽注流量的矩阵化计算方法,定量化对比分析了溶质质量比和天然地下水含量。结果表明:相较于原始抽注方式,将SYC-1和SYZ-1井的抽注方式互换后,地下水降落漏斗范围减小,抽液井对浸出液的捕获能力显著提升,抽出与注入的溶质质量比提升1.7倍,抽液量中的天然地下水含量降低29.4%,抽注液井间的水力联系更强,浸出效果优于原始抽注方式;钙质砂岩和泥岩夹层显著阻碍了抽注液井间的水力联系,导致不同抽注方式产生显著差异化的浸出效果。

Uneven and discontinuous calcareous sandstone and mudstone interlayers are distributed in the mining area of Bayin Qinggeli uranium mine. In order to explore the influence of low-permeability interlayers on uranium leaching effect, a three-dimensional unstructured grid lithology model of ore-bearing aquifer was constructed based on borehole data in the test mining area, and the flow field and solute transport process of in-situ leaching uranium under different extraction-injection methods were simulated. By introducing a matrix calculation method based on the actual extraction-injection flow of group wells, the solute mass ratio and natural groundwater content were quantitatively compared and analyzed. The results show that compared with the original extraction-injection method, after the extraction-injection methods of SYC-1 and SYZ-1 wells are interchanged, the range of groundwater drawdown funnel is reduced, the capture ability of pumping wells to leaching solution is significantly improved, the mass ratio of extracted and injected solute is increased by 1.7 times, the natural groundwater content in pumping volume is reduced by 29.4%, the hydraulic connection between extraction-injection wells is stronger, and the leaching effect is better than that of the original extraction-injection method. Calcareous sandstone and mudstone interlayers significantly hinder the hydraulic connection between extraction-injection wells, resulting in significantly different leaching effects of different extraction-injection methods.
