Neutral in-situ leaching uranium mining mine production drilling plug cleaning process

The invention belongs to a cleaning process, and particularly relates to a cleaning process for drilling blockages in neutral in-situ leaching uranium mining mine production. The invention relates to a neutral in-situ leaching uranium mining mine production drill hole blockage cleaning process which comprises the following steps: (1) a gas piston well washing process; and (2) a high-pressure intermittent well washing process. Compared with the prior art, the method has the following beneficial effects that mechanical blockages and chemical blockages of a liquid injection well are effectively removed through 10% diluted hydrochloric acid, gas piston and high-pressure intermittent combined well washing, the average liquid injection amount is increased by 3.69 m < 3 >/h after blockage removal, and the holding time is longer than 70 d. 本发明属于清洗工艺，具体涉及一种中性地浸采铀矿山生产钻孔堵塞物清洗工艺。一种中性地浸采铀矿山生产钻孔堵塞物清洗工艺，包括下述内容，⑴气活塞洗井工艺；⑵高压间歇式洗井工艺。本发明相对于现有技术具有以下有益效果：10％稀盐酸+气活塞+高压间歇式联合洗井有效解除注液井机械堵塞物与化学堵塞物，解堵后平均注液量提升3.69m3/h且维持时间大于70d。
