Mineral detection method and device

Abstract

The embodiment of the invention discloses a mineral product detection method, which is characterized by comprising the following steps of: analyzing the ore deposit type of an area to be detected to obtain an ore-forming model of the area; inputting geological information, remote sensing information and geochemical information into the mineralization model to obtain characteristic information; and optimizing the feature information by adopting an interpolation algorithm and a factor analysis algorithm to obtain an evidence layer; carrying out classification prediction on the feature information by adopting a pre-trained support vector machine model to obtain a mineralization detection map. According to the method, calculation of an evidence layer is adopted, so that few samples are needed for prediction, and the method conforms to the actual geological conditions with few known mine points during mineralization prediction; by combining a kernel function, data dimension conversion can be carried out, the solving difficulty of a high-dimensional space problem is reduced, and the calculation rate is increased; and based on a structural risk minimization principle, an over-learning problem is avoided, and the generalization capability is high.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mineral detection, in particular to a mineral detection method and device. Background technique [0002] In the process of modernization, the insufficient supply of resources has become a major bottleneck for the country's sustainable development, and gold resources are the top priority. Gold is not only a symbol to measure a country's economic strength and payment ability, but also has a wide range of industrial uses. Gold resources are the basis for the development of gold production, and all countries in the world attach great importance to the exploration and mining of gold mines. The northern margin of the North China Plateau is relatively rich in gold resources, with about 900 ore spots and a reserve of about 900 tons, accounting for about 20% of my country's gold reserves. The Jining shallow coverage area is located in the Wulashan-East Daqing section on the northern mar...
