Regional distribution characteristics of mine environmental geological problems in China

Abstract：This paper analyzes some distribution characteristics of main environmental geological problems resulting from the exploitation of mineral resources in different regions of China, and provides some basic information for programming of mine ecological environment recovery. The authors systematically divide national mine geological environmental areas and analyze geological environmental conditions. This paper generalizes distribution characteristics of land occupation and destruction, geological hazards, environmental contamination areas produced during the exploitation of mineral resources on the basis of studying mineral resources types, exploitation intensity in different geological environmental regions and main mine environmental geological problem types, distribution, hazards and some main mine environmental geological problems that require prevention and cure. The results indicate that the exploitation intensity of mineral resources and the mine environmental geological problems in middle and eastern China is much more serious than those in western China. Coal mines are much more serious than metal mines, and metal mines are in turn much more serious than non-metal mines in environmental geological problems.
