Background

The subsidence area refers to a subsidence area left after coal mining of a coal mine and is synonymous with the subsidence area. Comprehensive treatment of coal mining subsidence areas is generally considered to be a worldwide problem. Because the mineral resources reserves of the cities in which the mining subsidence areas are located are large, the distribution range is wide, the development time is generally long, and the production activities of the mining areas and the waste gas, waste water, waste residues and the like generated by the mining subsidence areas seriously pollute the surrounding environment. Mining subsidence destroys the form of the earth surface, so that the loss of soil nutrients and organic matters is accelerated due to the increase of the slope of the cultivated land, and the fertility is greatly reduced. Meanwhile, the agricultural infrastructure is damaged and destroyed, and the agricultural production environment is gradually worsened. The coal gangue is solid waste discharged in the coal mining process and the coal washing process, is a black gray rock which has lower carbon content and is harder than coal and is associated with a coal bed in the coal forming process, can be used for filling a coal mining subsidence area, and then is filled with soil to restore the form of the surrounding earth surface.
