Problems solved by technology

Since there is no simple linear relationship between the formation of ore deposits, metallogenic events, and various metallogenic control factors, the relationship between ore prospecting targets and various direct and indirect ore prospecting information is mostly non-linear, so It is of great significance to scientifically and objectively determine the weight of each information variable in 3D metallogenic prediction. mine availability

Abstract

The embodiment of the invention discloses a three-dimensional positioning metallogenic prediction method and system for a concealed ore body. The method comprises the steps that geological informationvariables used for performing concealed ore body metallogenic prediction and a three-dimensional data model of a known ore body are established, a geological space range is divided to perform cubic information unit processing, the geological information variables and spatial position registration data of the known ore body in cubic information units are acquired, and a Meta analysis algorithm isused to calculate and obtain a dominance ratio among the geological information variables; and weight values of the geological information variables on mineralization are determined according to the dominance ratio, a comprehensive evaluation value of each cubic information unit is acquired, and a metallogenic prediction target region is defined. Through the metallogenic prediction method and system, three-dimensional positioning metallogenic prediction precision and ore prospecting effectiveness of the concealed ore body are improved based on Meta analysis, a quantitative result of a processing effect can be given, the problem that research results are inconsistent is effectively solved, and an effective method is provided for objective determination of weights.

Description

technical field [0001] The present invention relates to the technical field of metallogenic prediction, in particular to a method and system for three-dimensional positioning metallogenic prediction of concealed ore bodies. Background technique [0002] At present, people's demand for mineral resources is increasing day by day, and at the same time, the outcrop mines and near-surface mines that are easy to find are decreasing day by day. A group of large and medium-sized mines have gradually exhausted their reserves, and most of them have entered the ranks of crisis mines. Therefore, searching for deep hidden ore bodies has become an important way for new breakthroughs in geological prospecting. At present, the prediction and evaluation of regional mineral resources based on two-dimensional or two-and-a-half-dimensional small-to-medium scales is difficult to adapt to and meet the requirements of large-scale mine replacement resource prospecting to the deep edge three-dimensi...
