摘要
Abstract
Low-permeability sandstone uranium mine,with its poor permeability and high injection dif-ficulty,has brought great challenges to the traditional in-situ leaching mining technology.In view of the current low permeability uranium mining problems,this paper discussed the innovative application of high-pressure liquid injection technology in the field of in-situ leaching mining and its effectiveness.Comparative tests were conducted to verify the effectiveness of high-pressure liquid injection technolo-gy,pumping liquid volume test and tracer test were carried out under atmospheric pressure and high-pressure conditions respectively.The test results show that compared with the atmospheric pressure condition,the high-pressure liquid injection technology increases the injection flow by 6.4 times,the pumping flow by 1.05 times and the seepage velocity by 33 times.High-pressure liquid injection tech-nology can effectively solve the leachants injection problem in low-permeability sandstone uranium mine,and the technology is convenient to implement in the mine site.关键词
