Description

technical field [0001] The present invention relates to the field, in particular to a multi-scale data unified expression method and system. Background technique [0002] Multivariate and unified characterization of deep metallogenic information, especially multi-dimensional and unified characterization of deep multi-scale uncertain metallogenic information. [0003] The biggest problem facing deep prospecting is that it is difficult to obtain useful prospecting information, and the obtained prospecting information is less effective in guiding deep prospecting due to its low reliability and strong multi-solution characteristics. To conduct sufficient excavation and comprehensive research on the obtained information about deep ore prospecting becomes the key to determine whether a breakthrough in deep ore prospecting can be achieved economically and efficiently. [0004] The traditional methods for evaluating the uncertainty of mineral prediction include probability theory a...

AI Technical Summary

Problems solved by technology

[0021] Deep ore prospecting has significant characteristics different from shallow ore prospecting, such as deep ore burial, weak mineralization information, and difficulty in ore prospecting. Difficulties have been encountered in metallogenic theory, geophysical and geochemical prospecting methods, and drilling techniques. : 1) The environment of deep mineral production is more complex, and traditional geological thinking is difficult to accurately predict the deep mineralization model, which has great uncertainty

2) In terms of geophysical prospecting, the qualitative interpretation of deep geophysical prospecting anomalies has multiple solutions and is difficult

3) In terms of geochemical prospecting, conventional geochemical prospecting methods are ineffective for deep deposits

4) High requirements for drilling

[0022] Because it is very difficult to obtain accurate information in the deep, and the accuracy of the obtained information is not high, coupled with the accurate understanding of the knowledge or information of the complex metallogenic system in the deep, it is very difficult to find ore in the deep
