Abstract: The natural conditions of Shendong Mining Area were terrible and the ecological environment was fragile and the traditional mining method would cause a non-restoration to the ecological environment.In order to solve the violent contradiction, with the production practices and technical innovation, an active type compre hensive prevention and control technical system of the ecological environment was provided, including the establishing technology of ecological prevention and protecti on function circle before the mining conducted, the mine clean mining technology during the mining period and the ecological system restoration and function optimizati on technology system after the mining completed. When the production scale of the mining area is over 200 million t, the ecological environment of the mining area woul d be effectively protected and improved.The technical system would be the access to the high intensity development of the coal resources in the ecological fragile zone and to the ecological environment protection and coordinative development.The green mining of the mining area was realized.
