With the continuous progress of science and technology, hyperspectral imaging technology has been widely used in geoscience, environment, agriculture and other fields. In underground mining, hyperspectral imaging technology is also widely used in ore body identification, ore grade estimation, and ore body internal structure detection. This article will focus on the application of hyperspectral imaging technology in underground mining and its future development direction.
1. Overview of hyperspectral imaging technology.
Hyperspectral imaging technology is a new type of spectral technology, which realizes fine spectral analysis and identification of ground objects by obtaining information on the continuous spectral band. Compared with traditional spectroscopic technology, hyperspectral imaging technology has higher spectral resolution and richer spectral information, which can more accurately reflect the physical and chemical characteristics of ground objects.
2. Application of hyperspectral imaging technology in underground mining.
1.Ore body identification.
Ore body identification is a key task in underground mining and one of the important applications of hyperspectral imaging technology. Through hyperspectral imaging technology, the reflectance spectral information of the ore body can be obtained, so as to realize the fine classification and identification of the ore body. In practical application, the corresponding classification standard can be formulated according to the spectral characteristics of the ore body, and the hyperspectral image can be used to segment and identify the ore body. At the same time, it can also be combined with geological data and exploration data to improve the accuracy and reliability of ore body identification.
2.Mineral grade estimation.
In underground mining, the estimation of mineral grade is of great significance for the rational utilization of resources and the formulation of mining plans. Hyperspectral imaging technology can obtain the spectral information of the ore body and use the correlation algorithm to achieve rapid estimation of the mineral grade. In practical applications, hyperspectral images can be used to segment ore bodies, extract mineral information of different grades, and classify and estimate according to their spectral characteristics. Compared with traditional sampling and analysis methods, hyperspectral imaging technology has higher efficiency and accuracy, and can provide more reliable support for mining decisions.
3.Exploration of the internal structure of the ore body.
The detection of the internal structure of the ore body is an important task in underground mining, which is of great significance for mining safety and the formulation of mining plans. Hyperspectral imaging technology can detect and analyze the internal structure of the ore body by obtaining continuous spectral information of the ore body. In practical applications, hyperspectral images can be used to fine-tune the ore body for fine imaging and segmentation, extract information on different mineral compositions, and analyze their distribution and structural characteristics. Through the detection and analysis of the internal structure of the ore body, it can provide more accurate and reliable data support for the formulation of mining plans and safety measures.
Third, the future development direction.
With the continuous progress of science and technology and the continuous improvement of application requirements, the application of hyperspectral imaging technology in underground mining will become more and more extensive. The future development direction includes the following aspects: first, improve the resolution and accuracy of hyperspectral imaging technology to meet the needs of more refined detection and analysis; The second is to strengthen the research on hyperspectral data processing and analysis algorithms to improve the ability to identify and classify minerals; The third is to explore the combination and application of hyperspectral imaging technology with other technologies, such as remote sensing technology and geological exploration technology, so as to improve the comprehensive detection ability and analysis effect; Fourth, strengthen the research on the practical application of hyperspectral imaging technology in underground mining, so as to improve its practical application effect and economic benefits in mining production.
