Abstract

The invention relates to a metallogenic prediction method based on fuzzy logic and machine learning. The method comprises the following steps: establishing an ore deposit model, wherein the ore deposit model comprises mineralization geological elements, a mineralization process and a mineralization effect; obtaining mineralization prediction elements related to mineralization based on the ore deposit model; preprocessing the mineralization prediction elements; fuzzy processing is carried out on the preprocessed metallogenic prediction elements; determining training data based on the mineralization prediction elements after fuzzy processing; establishing a machine learning model; training the machine learning model based on the training data to obtain a trained machine learning model; and performing metallogenic prediction based on the trained machine learning model. According to the method provided by the invention, the prediction accuracy can be improved.

Description

technical field

[0001] The invention relates to the field of metallogenic prediction, in particular to a method and system for metallogenic prediction based on fuzzy logic and machine learning. Background technique

[0002] Metallogenic prediction is a hotspot in the study of ore deposits, and it is a bridge and tool to guide ore prospecting. At present, the main metallogenic prediction methods can be divided into two categories: knowledge-driven and data-driven. Among them, the knowledge-driven method is suitable for metallogenic prediction in areas with few known mineral deposits, while the data-driven method is suitable for metallogenic prediction in areas with more known mineral deposits.

[0003] The commonly used data-driven metallogenic prediction method (such as the weight of evidence method) is to directly import each variable into the prediction model to generate a mineralization favorable map for metallogenic prediction. When applying variables, directly applyin...
