Abstract

The national mine remote sensing monitoring is an important basic national condition investigation work. Using remote sensing data in July 2022, through remote sensing interpretation and field verification, the remote sensing monitoring of open-pit mines in China was completed. The open-pit mining land in China is 993.4 thousand hm², accounting for 1.04‰ of the national land area, which is mainly distributed in Xinjiang Uygur Autonomous region, Inner Mongolia Autonomous region, Qinghai Province, Shanxi Province, Yunnan Province. Among them, the ecological rehabilitation rate of land damaged by mining is 9.57%. The area of open-pit mining land of chemical raw materials non-metallic, building materials and other non-metallic minerals and energy minerals is more larger than other minerals. The basic farmland is occupied by open-pit mining land , which is 11686.64 hm², accounting for 1.18% of the total area; the national open-pit mining land located within the ecological red lines is 7410.62 hm², accounting for 8.39 % of the total area. According to the above results, this paper preliminarily analyzes the current situation of mining damaged land distribution, ecological rehabilitation and existing problems in open-pit mines in China, and puts forward corresponding countermeasures and suggestions.
