Outline
Mineral resources are an important material foundation for human survival and development. To strengthen the research on regulatory technology for cross-border mining in open-pit mines, high-resolution remote sensing technology was proposed for dynamic monitoring of cross-border mining activities. Three periods of high-resolution remote sensing images were selected, the change information of cross-border mining patterns in open-pit mines with provincial and municipal certification in Xiangtan City was extracted, and remote sensing dynamic monitoring research was conducted on cross-border mining in open-pit mines. A remote sensing interpretation marker library was established for the development of open-pit mines in the research area, a relatively complete set of dynamic monitoring technology methods was explored for cross-border mining in open-pit mines. The accuracy of suspected cross-border mining and mining development of the map spot accounts for 100% and 90.3%, respectively. It is found that, from 2016 to 2020, the number, map spots, and total area of cross-border open-pit mines with provincial and municipal certification in Xiangtan City show an overall decreasing trend. The research results indicate that high-resolution remote sensing technology has a strong practicality and high accuracy in the dynamic monitoring of cross-border mining in open-pit mines, and can effectively monitor the dynamic changes of cross-border mining. The research results can provide a technical support for the dynamic monitoring of cross-border mining in open-pit mines in Xiangtan City.
