On the theory and techniques of eco-environmental harness of opencast mine

The eco-environmental harness of opencast mine has been an important part of ecological restoration in China.Opencast mining has made severe even fatal damages to the mines from its terrains,physiognomy to its soil,rock,and from its ecology scales to its landscape scales.This paper summarized the vegetation restoration technology of mine at present,and discussed the theory concerning eco-environmental harness,and finally pointed out some principles related to landscape for the control of mine eco-environment.
