THE SD-BASED MODEL OF UNIFICATION SYSTEM OF OPNE-PIT MINE PRODUCTION AND ITS ECOLOGICAL RECONSTRUCTION

Based on the analysis of environment-destroyed character of open-pit mine,and according to the buried-situation of ore deposit,the unification system of mining-reclamation and its impact on the ecological environment have been studied.According to the analysis of feedback relations between mining-reclamation and ecological reconstruction,a system dynamic model that integrates open-pit mine production and its ecological reconstruction has been modeled.
