摘要
地浸采铀矿山常用的洗井方法存在洗井效果不理想、洗井成本高等问题,采用负压洗井工艺在内蒙古某地浸采铀矿山开展了试验研究。结果表明,封隔器下放深度越大,洗井效果越明显;与压缩空气洗井工艺相比,负压洗井工艺更能提高钻孔瞬时流量,且瞬时流量保持时间更长。
There are some problems such as unsatisfactory well washing effect and high cost of well washing in the common washing methods of in-situ leaching uranium mines.The negative pressure well washing technology is used to carry out an experimental study in a leaching uranium mine in Inner Mongolia.The results show that the deeper the packer is,the more obvious the washing effect is.Compared with the compressed air washing process,the negative pressure washing process can improve the instantaneous flow rate of the borehole more,and the instantaneous flow retention time is longer.
