The main erosion strains in Shenfu-Dongsheng coal mining area are wind,water,gravity and human activities.The erosion strains have two features,that is,wind erosion and water erosion change periodly with the alternation of seasons and interlance with each other spatially.The interation of wind erosion and water erosion,as well as the process of erosion,transportation and deposition of earth surface caused by erosion strains have formed special micro-landforms on slope surface and vertical erosion belts.
