Abstract: Fragile ecological environment and strong mining intensity are the distinctive characteristics of the super-size mining face at aeolian sandy area. Thus, the ecological and environmental damages induced in aeolian sandy area are quite different from that in Eastern China. The environmental damage process has been divided into four stages in this paper: strata failure, ground subsidence, habitat change of the animal and vegetation, and succession of the ecology system at the mining area. The formation and changing rule of ground fissures, distribution soil moisture, changes of groundwater, and plant spe- cies diversity & coverage under the impacts of underground coal mining have been analyzed. Finally, the paper has put forward the idea that the countermeasures for the ecological restoration at aeolian sandy area should not only focus on ecology protection but also remediation, taking both different damage conditions of the environmental factors and objectives of the ecological restoration into ac- count.

Key words: Erdos coalfield, ecological restoration, high intensity mining, aeolian sandy site
