Abstract: The exploitation of mineral resources on the surrounding ecological environment is increasingly serious.The mining area ecological environment security is receiving increasing attention.There are many factors of influence on mine ecological environment safety and the mechanism of action is complex.Therefore, looking for the latent structure and the key variables is the most basic problem to solve the mine ecological environment safety.Application the interpretative structural modeling method of system engineering to analysis the factors of influence on the mine ecological environment safety, the interpret structure model was established.According to the key factors, countermeasures were proposed .

Key words: Ecological environment, Safety, Interpretative structural model
