Outline
Conventional ecological restoration surveys in mines have the characteristics of long time, high cost, and difficulty in tracing the past, which have certain limitations. In order to quickly and intuitively obtain the distribution and restoration progress of historical abandoned mines in aimed region, taking northwest Yunnan as the research area, multi temporal remote sensing data was used to summarize the interpretation indicators of distribution in historical abandoned mines, mine ecological restoration models, and specific restoration measures in this area. Through conducting detailed interpretation and analysis and combining with field investigation and verification work, the distribution of historical abandoned mines in this area and the subsequent ecological restoration situation of mines were clarified. The results show that there are a total of 3 060 historical mining spots in this area, with mining and transfer sites as the main types of damage, accounting for 81.8% of the total number of spots. The involved minerals are mainly non-metallic minerals. In terms of mine restoration, 765 mining spots with an area of approximately 1 468 hectares have been repaired and treated, mainly through engineering restoration. The investigation and research results can provide a reference for the investigation and restoration of abandoned mines, as well as important data support for the planning, policy formulation, and deployment of mine ecological restoration and management work.
