Abstract: 3R principles of cyclic economy are applied in planning the ecological construction of Ma Steel's Heshangqiao Iron Mine which is to be put into operation soon. In the plan, the engineering construction of its mining and mineral processing will make a full use of the existing facilities of Ma Steel's Nanshan Mine, thus saving a great amount of engineering investment. In the mining process, only the iron ore will be mined out as the product while the burden, waste rock and sewage will be utilized as resources. When the mine is closed, its pit and tailing reservoir will be reclaimed in a scientific manner to create a new tourist spot connecting with Caishiji senior area so as to form a tourist scene line consisting mountain, river, lake and garden. The ecological construction of Heshangqiao mining area will bring along that of Ma Steel's Nanshan mining area and of the eastern Maanshan so as to promote the development of Maanshan City towards an ecological one.
