摘　　要：概述了提高卷状矿床翼部矿体浸出液ρ(U)的措施:对已建采区,调整钻孔抽注功能,增加富矿、厚矿部位抽液孔的液位降深,同一钻孔适时调换抽注功能等;对新建采区,改进钻孔结构、施工及成井工艺,以及过滤管排列形式等。实践证明,这些措施是行之有效的。Measures to raise uranium content in pregnant solution from ＂tails＂ of roll-type ore body are discussed, including adjusting the pumping injecting function of well, increasing the drop of water table of pumping well in high grade ore and thick ore for the built mining block; improving well structure, construction and well completion technology, and location of filter for the new mining block to be built, ect.

关 键 词：翼部矿体 铀质量浓度 开采 改进措施
