The study of metallogenic belts can provide a basis for mineral monitoring and deployment. Research of the metallogenic belt in Zhejiang Province is too deficient. This paper uses the domestic high-resolution satellite data from 2018 to 2021 to carry out the application of remote sensing in a comprehensive geological survey on different metallogenic belts in Zhejiang Province. The survey results show that the area of each metallogenic belt is decreasing year by year, which shows that under the regulation of the natural resources department, the unqualified mining activities in key control areas such as nature reserves, ecological red lines, and the Yangtze River economic belt are timely stopped and forcibly closed, so that the mining development order gradually tends to be good. The restoration and control points show a trend of less in the south and more in the north, mainly distributed in the economically developed areas of the northern, central, and eastern plains of Zhejiang Province. According to the statistics of the degree of mine environment restoration and treatment (treatment percentage), the Taishun-Zhoushan metallogenic belt is the highest, and treatment percentage from 2018 to 2021 is 83.01%, 80.07%, 76.91%, and 73.78%, respectively. For four consecutive years, the number of restoration and treatment projects has been increasing, and the restoration and treatment area has increased significantly. The countermeasures and suggestions for mine environmental restoration in the metallogenic belt have been put forward. In the mining area, if the geological environment is good, the rainfall is sufficient, and so on, then natural re greening can be considered. According to the brief evaluation criteria, a total of 2983 mines can be restored naturally, including 311 in the Si’an-Changxing metallogenic belt, 325 in the Lin’an-Huzhou metallogenic belt, 387 in the Kaihua-Hangzhou metallogenic Belt, 598 in the Quzhou-Shaoxing metallogenic belt, 765 in the Longquan-Shangyu metallogenic belt, and 597 in the Taishun-Zhoushan metallogenic belt. A total of 1911 mines were involved within 1 km of the “three zones and two lines”. There are 50 places in the Si’an-Changxing metallogenic belt, 151 in the Lin’an-Huzhou metallogenic belt, 236 in the Kaihua-Hangzhou metallogenic belt, 326 in the Quzhou-Shaoxing metallogenic belt, 513 in the Longquan-Shangyu metallogenic belt, and 635 in the Taishun-Zhoushan metallogenic belt. The survey results and suggestions can provide scientific basis and important reference for the local mining administration department to carry out the restoration of the mine ecological environment in metallogenic belts, and they are of great significance to promote the wide and in-depth application and technological progress of remote sensing technology.
