Abstract: It is a substantial issue for land reclamation of surface coal mine in arid grassland that soil erosion of open pit coal mine leads to soil salinization and surrounding grassland degradation.Taking the dump of No.2 surface coal mine in Shenglidong mining area in Inner Mongolia as a case.The research method is the combination of on-site investigation and data analysis.The results indicate:①There are three typical limiting factors for land reclamation such as insufficient surface soil, water shortage and few suitable species in arid grassland.②Meanwhile, the corresponding engineering measures in Shenglidong mine include removing and covering topsoil, using mat to prevent soil erosion; biological measures involve the application of organic fertilizers and reasonable allocation of herbage, bush and arbor.The results can be technological reference for the similar land reclamation.

Key words: Arid grassland, Surface coal mine, Land reclamation, Technology analysis
