Application Of Integrated Logging Technology In The Production Of Uranium By In-situ Leaching

With the world energy increasingly tense,the industrial application status of uranium is becoming more and more prominent.In-situ leach uranium deposit is the type with the largest reserves of uranium resources,and is also the focus of global uranium exploration strategies.In particular,in-situ leach sandstone uranium deposit with low grade,large amount of ore,easy leaching and low cost have always been the focus of research in various countriesSince the mid-1990 s,China has made a breakthrough in the in-situ leaching of uranium in the northwest region of China by investigating,introducing,learning and absorbing the successful experience of Russia,Ukraine and other countries in uranium mining,and combining the distribution characteristics of uranium deposits in China.As the exploration of in-situ leachable sandstone-type uranium mining work of deepening,China make full use of multi-parameter comprehensive logging information technology to solve many problems in theory and practice,combined with the digital data acquisition and data interpretation,increased the underground orebody information ability,for the development of uranium and the mode of production is also in constant change.At present,integrated logging technology has become more and more important in the ore-forming environment,ore-forming rules and uranium mining of in-situ leachable sandstone-type uranium deposits.As a branch of geophysical exploration,logging technology has been widely used in uranium exploration and mining.From the perspective of industrial production of in-situ leaching,the following work were carried out in this paper.By collecting the geological and in-situ leaching production data of a certain in-situ leaching mine in xinjiang,the fitting idea and mathematical analysis of the integrated logging resistivity value of a certain in-situ leaching area to estimate the permeability coefficient of theore-bearing aquifer were carried out.Combined with the drilling project of exploitation of uranium deposits,the combined logging and core cataloging work were carried out,and the application of geophysical integrated logging technology in uranium production by in-situ leaching was studied,so as to find a method for estimating the permeability coefficient of ore-bearing aquifer by integrated logging resistivity value and applying it to in-situ leaching production.The following results were obtained.The data processing of "resistivity estimation of permeability coefficient" and the method of fitting the empirical formula were realized by mathematical statistics.The regional permeability coefficient was obtained by data processing and empirical formula fitting under different deposit conditions,and it was successfully applied to the industrial production of in-situ leaching.Strengthening geophysical integrated logging technology plays an important role in the industrial production of in-situ leach uranium.
