Method for rapidly achieving earth surface filling and reclamation soil forming of high-water-level coal mining subsidence area

The invention discloses a method for quickly realizing earth surface filling, reclamation and soil formation of a high-water-level coal mining subsidence area, and relates to the technical field of land reclamation, and the method comprises the following steps: S1, determining the position and area of a to-be-filled reclamation area; determining the filling thickness; s2, dividing the to-be-filled reclamation area into a plurality of strip-shaped reclamation areas according to the area and the surface form of the to-be-filled reclamation area; then the filling direction is determined; s3, filling the odd-number strip-shaped reclamation areas, extracting a bottom mud mixture in a water accumulation area, then sequentially filling slope top areas, slope land areas and slope bottom areas in the strip-shaped reclamation areas, and after filling of the odd-number strip-shaped reclamation areas is completed, arranging a stacking layer on the odd-number strip-shaped reclamation areas; and S4, preparing to fill the r
