【摘要】 目前对原地浸出采铀的研究主要有室内实验、现场试验和数值模拟3种途径。由于地浸过程发生于地下含矿含水层,是一个多场多过程耦合动力学复杂系统,其过程较难观察和监测,使得运用室内实验和现场试验的研究存在一定的局限性。随着计算机技术的发展、地下水动力学理论研究的深入,数值模拟方法日益受到人们的关注与重视。介绍了地浸采铀数值模拟研究的内容、常用的软件和国内外研究现状,提出了存在的问题以及发展方向。更多还原

【Abstract】 At present,there are three methods in studying on in-situ leaching of uranium,which are laboratory experiment,field test and numerical simulation.Because the leaching process occurred in the underground aquifer,it is a complex multi-field and multi-process coupled dynamical system.It is difficult to observe and monitor the process,making the use of laboratory experiment and field test have certain limitations.With the development of computer technology and the deepening of the theoretical study on groundwater dynamics,numerical simulation of in-situ leaching of uranium has attracted much concern and attention.This paper describes the contents and frequently-used software of the numerical simulation and research of in-situ leaching of uranium,introduces the present situation of domestic and foreign researches on the numerical simulation of in-situ leaching of uranium,and puts forward the main existing problems and the trend of development.更多还原
