Zaoquan Coal Mine is located in the southwest margin of Mu Us Desert,which is in the arid and sandy desertification area in northwest China.In order to scientifically and effectively eliminate the pollution hazards of coal gangue caused during the development and production of coal energy in Zaoquan Coal Mine,the reasonable,applicable and practical land reclamation and treatment-coal gangue engineering technology mechanisms and systematic,three-dimensional and composite design schemes were formulated scientifically;through the standardized and strict construction and implementation of the gangue retaining walls,flood dis-charge structures,soil covering works,the bottom leveling of gangue backfill yard,flood dam construction and planting of plants,the coal gangues were backfilled promptly to completely eliminate any harm to environ-ment caused by coal gangue,so as to implement high-quality and high-efficient land reclamation engineering techniques,achieve the purpose of coal gangue control through green science and technology innovation,high-light the comprehensive management and promotion of the scientific system of coal gangue,as well as the in-tegration of economic,social and environmental benefits of high-quality energy development in mining areas,thus achieving the sustainable development of Zaoquan mining area.
