Mineral prospecting method and device based on geoscience information, electronic equipment and storage medium

Abstract

The invention provides a nonlinear quantitative mineral prospecting method and device based on geoscience information, electronic equipment and a storage medium, and the method comprises the steps of collecting geological data in a research region through field geological investigation, and carrying out the verification of the collected geological data; storing the geological data in the form of a grid picture, geometrically correcting and vectorizing the geological data of the grid picture, and endowing elevation and corresponding attribute values; traversing all layers of the raster picture according to the verniers of the layers; calculating a prior probability P prior and a prior favorable degree O prior of the research area; and generating a prediction result in the research area according to the posterior probability value of each block unit in the research area. According to the invention, fractal and multi-fractal methods are applied to determining the abnormal lower limit of part of mineral prospecting marks and grading metallogenic prospecting areas, so that the mineral resource distribution of a research area is more accurate.

Description

technical field [0001] The invention relates to an intelligent prospecting technology, in particular to a non-linear quantitative prospecting method and device, electronic equipment and a computer storage medium based on geological information. Background technique [0002] In recent years, the prospecting prediction evaluation of mineral census and exploration tends to be computer application, especially based on Geographic Information System (Geographic Information System, GIS) technology has always been an important technical means for quantitative geoscience and geoinformatics researchers at home and abroad. Based on two-dimensional ( 2D) or 3D (3D) GIS multivariate metallogenic geology information (geology, geophysics, geochemistry and remote sensing) extraction and integration has become a technical method system for mineral resource evaluation, and is still an important research field for mineral exploration and evaluation at home and abroad. content. This system is ...

Problems solved by technology

This system is universal for two-dimensional (2D) regional resource evaluation of small and medium scales, but there are still many deficiencies in the evaluation of large-scale three-dimensional (3D) space mineral resources above 50,000, especially in the location prediction of deep hidden mines It is obviously lacking in estimating the amount of mineral resources and metal resources, mainly because of the constraints of 3D visualization of geological bodies, the lack of necessary 3D spatial analysis technology and the extraction and integration of ore-causing anomaly information
