Problems solved by technology

However, it has become the main trend of uranium ore exploration in various countries and regions to attack depth and find blindness. With the continuous development and improvement of 3D visualization technology, the traditional two-dimensional analysis method can no longer meet the needs of existing uranium ore exploration.

Abstract

The invention belongs to the technical field of uranium mines, and particularly relates to a method for constructing a three-dimensional geological model of a calcrete type uranium mine. The method comprises the following steps of: (1) systematically collecting various related data according to a range of a mining region or a working region; (2) sorting out an inclinometer table, a positioning table, a grade table and a lithology table on the basis of the data collected in the step (1), and establishing a geological space database of the working region or the mining region on the basis of a 3Dmine platform; (3) extracting various modeling objects in a layered manner, and performing element extraction in the 3D mine platform to generate a layered file; (4) and finishing three-dimensional geological modeling in GOCAD three-dimensional software by utilizing the layered arrangement data obtained in the step (3). According to the method, the spatial distribution condition of the mineralized layer can be quickly and accurately locked, the blindness of peripheral and deep mineral exploration is reduced, the time and the cost are saved, and an important technical support is provided for the exploration of the calcareous uranium deposit.

Description

technical field [0001] The invention belongs to the technical field of uranium ore, and in particular relates to a method for constructing a three-dimensional geological model of calcareous uranium ore. Background technique [0002] The development trend of geological models is from a single model to multiple models; from a two-dimensional model to a three-dimensional model; from a single-source information model to a multi-source information model. In short, with the deepening of the understanding of metallogenic laws and the continuous popularization and application of high-tech in the field of mineral exploration, the perfection, comprehensiveness and representativeness of geological models will continue to improve, and the guiding significance for predicting ore prospecting will continue to increase. getting bigger. At present, the establishment of geological models of uranium deposits is mostly focused on two-dimensional, and there is no mature technical method for the...
