摘　　要：对我国某铀矿床进行了酸法地浸现场试验研究,在地浸过程中出现了化学堵塞、钻孔抽注液量显著降低的现象.根据铀、钙、铁、铝的浸出曲线,分析了造成该矿床化学堵塞的成因,并通过化学洗孔试验进行了验证.结果表明,铀、铁、铝形成暂时性堵塞,而钙形成永久性堵塞.The field test of acid in - stiu leaching in the uranium deposit has been finished, the results show that the chemical jam has been produced and that flowate of of production/injection has been declined. According to the leaching curves of uranium, calcium,iron and aluminium, the causes of chemical jam are discussed in this paper. The results show the temporary jam is from uranium, iron and aluminium and that permanent jamming is from calcium.

关 键 词：酸法地浸 暂时性堵塞 永久性堵塞
