Abstract: Till now,the exploitation of Dahongshan iron ore of Kunming Iron and Steel has caused damage to the ecological environment within the mining area.To ensure sustainable development of the ecological environment and the mining production,land reclamation within the mining area were made by Dahongshan Iron Mine.Through analysis of different landforms and ecological damage at different altitude within mining area of Dahongshan Iron Mine,the mines are classified according to different terrain corresponding to different climatic conditions.The appropriate land reclamation measures and the biological configuration approach are proposed for different terrain and different vegetation systems for vegetation construction.For slopes and platforms,nurseries,forest,mixture drilling of tree,shrub and grass,mix sowing of shrub and grass,and creepers are proposed.By this method,the waste rock dump with site area of 83.11 hm2 can realize land reclamation rate of 99.80% to maximize social,ecological and economic benefits.Combined with domestic and international mining experiences,recommendation on mine ecological restoration and environment protection is given.
