Method for processing coal gangue and red mud

The invention discloses a method for processing coal gangue and red mud, which belongs to the technical field of pollution treatment of the coal gangue and the red mud, and aims at solving the technical problem to provide a layer upon layer piling method which is low in cost and can reduce environment pollution of the coal gangue and the red mud in maximum limit. The technical scheme is that the coal gangue and the red mud are laminated and piled, wherein a bottom first layer is provided with the coal gangue, a bottom second layer is provided with the red mud, and then the coal gangue and the red mud are alternately laminated and piled layer upon layer, at last the red mud is laminated and piled on a top layer, the thickness of the coal gangue on the first layer on the bottom first layer is 60-500cm, the thickness of the red mud on the bottom second layer is 5-100cm, the thickness of the red mud on the top layer is 30-50cm, and the thicknesses of the other layers are 5-15cm.
