| 中文摘要: |
| 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。 |

| 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 operations in drillings were studied to increase the water yield of wells.The test results indicated 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 between before and after test.Using vacuum operations is an effective method for strengthening production of in situ leaching of uranium and can be applied to in situ leaching mines |
