Preliminary analysis of mine geo-environment status and existing problems in China

Remote sensing monitoring of the mine is a basic survey with Chinese characteristics.Occupied and damaged land of the mines in 2014 covers an area of 220.42 million hm2 in China, accounting for 0.22% of the total land area.The mining mines cover an area of 113.48 million hm2, the abandoned mines cover an area of 98.25 million hm2, and the mine geo-environment recovery area covers an area of 8.69 million hm2.211.73 million hm2 of land have been occupied and damaged by the mines in national land, which include 149.33 million hm2 of damage and 62.40 million hm2 of occupation.4716 mine geological disasters were delineated in 2014, including 1887 collapses caused by mining activity, 1296 landslides, 1093 avalanches and 440 debris flows.In addition, the management suggestions or countermeasures are discussed, and the orientations for further research in the field are forecast.
