Abstract:
In order to understand the status quo of mine environmental restoration and governance in Henan Province in real time and quickly, the remote sensing images were used to investigate the status of mine environmental restoration and governance in Henan Province in 2019 by combining indoor interpretation with field verification.The results show that the open-pit stope occupies the most land in all the mines.Compared with 2018, in 2019, the area of mine restoration and treatment in the province increased significantly. In 2019, the area of mine restoration and treatment was 12, 175.57 hectares, an increase of 2, 235 hectare compared with 2018. Among them, the area of open-pit stope restoration and treatment was large and the recovery effect was good, while the abandoned land of mine, such as gangue hills and dumps, needed to accelerate the restoration and treatment.According to the statistics of interpretation results, there are still some mines that have not been restored, and there are some individual mines that have cross-border mining, disorderly mining, random digging and other phenomena. These illegal mining mines have a great impact on the environment.The results of the survey can provide reference for the environmental restoration and supervision of mines in Henan.
