Orthogonal-contour geometrization of hydrogenetic ore mineralizations

Abstract

The article presents an innovative approach to the geometrization of ore bodies during exploration work based on geophysical and/or core studies in wells for the purpose of areal and thickness delineation of hydrogenetic ore mineralization. The method makes it possible to obtain more accurate contours of ore bodies with a minimal increase in the number of wells constructed for this purpose. The method can be used in planning and conducting exploration work on hydrogenetic deposits. On the example of reservoir-infiltration uranium deposits of the Shu-Sarysu uranium ore province located in South Kazakhstan, shortcomings in the geometrization of ore bodies using the traditional method of placing of geological exploration wells are demonstrated, as well as the shortcomings of the proposed in literature methods of ore geometrization and the main advantages of the proposed innovative approach. The developed method solves a number of significant problems in the subsequent planning and implementation of mining and preparatory work at hydrogenetic deposits, contributes to a significant increase in the accuracy of the geometrization of ore bodies and calculation of reserves, and increases the reliability and investment attractiveness of explored hydrogenetic deposits. This method can also be used to save money by reducing the number of wells being constructed, if used for an inverse problem in order to discharge placement of exploration wells in middle part of ores bodies in hydrogenetic fields with a dense drilling grid.
