Abstract:The conventional ecological restoration investigation of mines has the characteristics of high cost and difficulty in tracing the past, which has certain limitations. In order to quickly and intuitively obtain the distribution and restoration progress of abandoned mines in the region. Taking northwest Yunnan as the research area, multi-temporal remote sensing data were used to summarize the interpretation signs of abandoned mines, mine ecological restoration models and specific restoration measures in the area, and detailed interpretation and analysis were carried out. Combined with the field investigation and verification work, the distribution of historical mines in the area and the subsequent ecological restoration of mines were found out. The results show that there are 3060 historical mine spots in the area. The main types of damage are stopes and transit sites, accounting for 81.8 % of the total number of spots, and the minerals involved are mainly non-metallic minerals.In terms of mine restoration, a total of 765 restoration and management map spots were completed, with an area of about 1468 hectares. The restoration method was based on engineering restoration. The research results can provide reference for similar abandoned mine investigation and restoration management, and also provide important data support for mine ecological restoration planning, policy formulation and project work deployment arrangement.
