System and method for monitoring and pre-warning for illegal exploitation of ionic adsorption rare earth ore

Abstract

The invention provides a system and a method for monitoring and pre-warning for illegal exploitation of ionic adsorption rare earth ore. Based on IKONOS satellite remote sensing data, the system and the method establish interpretation signs of illegal exploitation of the ionic adsorption rare earth mine in combination with mining right data, carry out pre-warning analysis on unexploited areas of a rare earth mine in combination with geological rock mass data, and provide a good technical means for fast, accurate and dynamic monitoring and pre-warning for the ionic adsorption rare earth ore mine. The system comprises a satellite remote sensing image acquiring unit, a remote sensing image processing unit, an illegal exploitation monitoring analysis unit and an illegal exploitation pre-warning analysis unit, wherein the satellite remote sensing image acquiring unit is used for acquiring original remote sensing image data, the remote sensing image processing unit is used for pre-processing the original remote sensing image data, the illegal exploitation monitoring analysis unit is used for establishing the interpretation signs of the illegal exploitation of the ionic adsorption rare earth mine, and the illegal exploitation pre-warning analysis unit is used for establishing sings of pre-warning areas which need to be monitored intensively.

Description

technical field [0001] The invention belongs to the field of remote sensing technology and application, in particular to a system and method for monitoring and early warning of illegal mining of ion-adsorption type rare earth mines based on IKONOS satellite remote sensing data. Background technique [0002] Ion-adsorption rare earth ore is a new type of rare earth ore discovered in Jiangxi, my country in 1969. The ore has the advantages of wide distribution, abundant reserves, low radioactivity, complete distribution of rare earth, and rich in medium and heavy rare earth elements. It is currently unique to our country. Rare earth mineral resources are also rare minerals in the world. They are widely distributed in Jiangxi, Fujian, Hunan, Guangdong, Guangxi and other provinces in southern my country, of which Jiangxi Province has the largest share. In recent years, due to the increasing demand for rare earth resources at home and abroad and the rising value of rare earths, the...

AI Technical Summary

Problems solved by technology

[0003] Ion-adsorption type rare earth mines are generally distributed in the mountains, and the transportation is inconvenient. It is not only time-consuming and labor-intensive to use ordinary monitoring methods, but also the work efficiency is very low, and the difficulty of mine management is relatively large.
