| 摘 要： | 提高钻孔抽液能力是原地浸出采铀生产过程中的关键问题.本文采用在空气提升溶液的条件下，配上钻孔的真空作业来增加钻孔涌水量.试验表明，采用真空作业时钻孔的涌水量均有所增加，而且较稳定，平均增长率为20.3%.同时发现试验前后溶液的酸度和金属铀浓度变化甚微.采用真空作业，是强化地浸试验和生产过程的有效手段，可在地浸矿山推广应用.

| Abstract: | Improving the pumping capacity of wells is a key issue for the production of in-situ leaching of uranium mining. Under the condition of air lift of solutions,the vacuum op-erations in drillings were studied to increase the water yield of wells. The test results indi-cated that the water yield of wells had increased and were stable, the average increasing rate was about 20 . 3%. The acidity and uranium concentration of solutions vary little be-tween before and after test. Using vacuum operations is an effective method for strengthe-ning production of in situ leaching of uranium and can be applied to in situ leaching mines. |
