Abstract:: Opencast mining has led to severe land damage and intricate site conditions, only by taking full accounts of environmental factors and ecological habits of vegetation and, according to different site types, conducting appropriate vegetation configuration and management can make the goal of ecological restoration of mining area achieved. Thus, the western dump of Antaibao opencast coal mine was selected as the site, 58 samples were taken in this research site. Within the scope of 10 m×10 m at each sample plot, the total amount of 18 site factors were examined, such as altitude, aspect, slope position, slope, slope type, soil matrixes, soil thickness, soil bulk density, soil water content, organic matter content, total nitrogen content, vegetation type, NDVI, non-uniform settlement of ground, relief degree of land surface and rivers momentum index. Based on the analysis of site conditions and characteristics of dump, site type was divided by using the clustering analysis method of SPSS. The study area was eventually divided into 2 site areas: the platform and the slope. The platform area was classified into 9 site groups and 13 site types; similarly, the slope area was divided into 9 site groups and 20 site types. This classification can provide the guidance for the improvement of mine site conditions, vegetation restoration and maintenance as well as the local ecosystem restoration.
