Abstract：Based on eco-industrial chain analysis of mining area, three eco-industrial chain types of mining area were divided into production eco-industrial chain, surplus eco-industrial chain and energy eco-industrial chain, and pointed out that the industry structure of eco-industrial chain in mining area were made of precursor industry, delivery industry and bottom industry. Based on above research, the link modes of mining ecologic industry chain were constructed creatively and the characteristics of group, asymmetry and progressive elaboration of ecology industry chain (net) of mining area were described systematically. Multi-objective linear optimal model was set up based on industry scale optimization of eco-industrial chain in mining area. Put forward some measures taken by mining area. That is, when the surplus scale of active industry unit exceeds the absorbing scale of passive industry unit, mining area can enlarge the passive industry unit scale and deal with the surplus material outside the industry chain (net) , adversely, the mining area should decrease the passive industry unit scale or get the surplus material from outside of industry chain (net) , and when the two scales are same, industry chains ( net) unit of eco-mining area is coordinated.
