This paper briefly introduced geographic and geological conditions of the Niutoushan cement-use limestone mine and mining method, discussed the issues of land loss and occupation, landforms destruction and collapse, landslide and other geological hazards that all resulted from mining. According to the geological environment features of the mine, a series of countermeasures have been made, such as intercepting ditch engineering, retaining wall engineering, slope and temporary yard clearing engineering, rock hole-opening engineering, road maintenance engineering, soil recovering engineering, tree-planting engineering, conservation management engineering and so on. Further, an emphasis was laid on the implications of geological environment treatment to recovering ecological environment of the mining area.
