Method for positioning and predicting ore body by utilizing three-dimensional geological modeling technology

Abstract

The invention belongs to a working method for uranium ore geology comprehensive research and particularly relates to a method for positioning and predicting an ore body by utilizing the three-dimensional geologic modeling technology. Traditional uranium mine detection has problems that subjectivity is high, the data processing and analyzing process is rough, and a generated image is not vivid enough. The method comprises steps of step 1, collecting data; 2, analyzing and processing the data; 3, establishing a model unit; 4, adjusting the pairing relationship; 5, establishing a small sequence model; and step 6, establishing an overall model. The method is advantaged in that the three-dimensional geological modeling technology is used for positioning the sand body, quantitative data and parameters of a sand body at all angles in the plane and the vertical direction are achieved, a distribution rule of the sand body is quantitatively and visually displayed, mineralization prediction precision is improved, prospecting efficiency is improved, and expenditure investment is saved.

Description

technical field [0001] The invention belongs to a working method for comprehensive geological research of uranium ore, in particular to a method for locating and predicting ore bodies by using three-dimensional geological modeling technology. Background technique [0002] Uranium resources are an important guarantee for the sustainable development of my country's nuclear energy and national defense construction. In order to ensure the sustainable development of my country's economy and the construction of ecological civilization, nuclear energy, as one of the clean energy sources, plays an important role in adjusting and optimizing my country's energy structure, improving the ecological environment and reducing CO 2 and S emissions are of great significance. In-situ leachable sandstone-type uranium deposits have become one of the main fields of uranium exploration in the world because of their advantages such as low mining cost, good mining effect, large reserves, and low e...

AI Technical Summary

Problems solved by technology

The limitations of this method are:

[0005] (1) Human factors such as subjectivity, preference, and habitual characteristics of geologists' own geological knowledge greatly affect the objective inference of sand body distribution characteristics, and are greatly influenced by humans

[0006] (2) The uniformity of the data distribution, the accuracy of the collected drilling data, and the possible errors in the process of manual data processing and analysis also affect the accuracy of inferring sand bodies and ore bodies to a certain extent

[0007] (3) The traditional two-dimensional maps lack three-dimensional sense, and the characterization of the three-dimensional spatial distribution characteristics and distribution laws of sand bodies is often not intuitive and vivid.
