In the construction and production processes of Shiyaodian coal mine,vegetation on the soil surface may be destroyed to a certain extent,soil structure may be significantly changed,some existing soil and water conservation facilities may be damaged,and a large number of discarded soil and dregs may be produced at the same time.In view of the existing problems of serious soil and water loss and deteriorating ecological environment in the construction and production stages,the area of disturbed primary landform,the area of land damage and vegetation destruction,the total amount of disposed soil and dregs,the damaged area and amount of soil and water conservation facilities,and the possibly increased amount of soil erosion by water and wind are predicted based on the investigation information and the analyses of related data and documents.The results of the predication can provide a scientific foundation and technical supports for rational implantation of the measures for soil and water conservation and ecological rehabilitation of Shiyaodian coal mine.
