The invention provides a comprehensive treatment method for restoration of gangue hill ecological environment. The method specifically comprises the following steps of carrying out gangue hill slope cutting, shaping and fire extinguishing engineering, carrying out enclosure and isolation engineering, carrying out soil covering engineering, carrying out semi-flexible rapid drainage system engineering, carrying out nutrient soil construction engineering, carrying out anti-erosion vegetation restoration engineering and carrying out vegetation maintenance system engineering. According to the method, through reasonable gangue hill slope cutting and a semi-flexible rapid drainage system, a gangue hill can be ensured to be safe and stable; through gangue hill fire extinguishing and enclosure andisolation, the damage to the gangue hill can be thoroughly eliminated; through scientific and reasonable soil improvement through soil exchange, vegetation can grow fast and permanently; through an anti-erosion vegetation restoration technology, the erosion of wind and rain to a side slope can be resisted; and a reasonable vegetation maintenance system is designed, so that the problems of vegetation irrigation and fertilization of the side slope of the gangue hill can be solved, and water and soil loss of the side slope of the gangue hill can be prevented. The method has the advantages that acombination of measures are taken from the seven key points, so that the damage of spontaneous combustion of the gangue hill to the environment can be avoided, a plant community can be quickly formed,and the restoration of the mine ecological environment can be realized.
