分析了原地破碎浸铀的矿床地质条件、水文地质条件、工程地质条件和工艺矿物学特征,认为原地破碎浸铀技术的顺利实施决定于不同的地质因素。以前铀矿床的勘探和地质条件的评价是基于传统的开采方法来评定的。为了采用原地破碎浸出采矿法来开采矿床,有必要对以前勘探的矿床进行开采前的重新评价,或在新勘探这类矿床时按原地破碎浸出采矿法所需的地质条件来评价。介绍了莫西涅茨.B.H所提出的对采用原地破碎浸出采矿法开采的矿床进行可行性评估的方法,并认为该评估方法对我国铀矿床开采前地质条件的评估具有指导性意义。另外以某铀矿床为例,采用莫西涅茨.B.H法进行了原地破碎浸铀的可行性评估。
The geological conditions, hydrogeological conditions, engineering geological conditions and process mineralogy features of in-situ broken leached uranium deposits are analyzed. It is considered that the smooth implementation of in-situ broken uranium impregnation technology depends on different geological factors. Previous uranium deposit exploration and evaluation of geological conditions were based on traditional mining methods. In order to exploit in-situ crushing and leaching mining methods, it is necessary to re-evaluate the previously-explored deposits before mining or to evaluate the geological conditions required for on-site crushing and leaching mining methods in the new exploration of such deposits. This paper introduces the method of feasibility assessment proposed by Mosinides B.B.H.M. on the deposits exploited by the in-situ crushing and leaching method, and holds that this method is of guiding significance for the assessment of geological conditions before the exploitation of uranium deposits in our country. In addition, taking a uranium deposit as an example, the feasibility assessment of in-situ crushing of impregnated uranium was conducted by using the Mönites method. B.H.
