Method for locally taking soil to reclaim mining subsidence areas of thick coal seams of mining areas

The invention discloses a method for locally taking soil to reclaim mining subsidence areas of thick coal seams of mining areas, which belongs to the technical field of mining, and is used for solving the problems of poor quality of reclaimed soil, difficult subsequent soil improvement and the like in the reclamation technology for cultivated land of the mining subsidence areas. The technical scheme is that the method is implemented by the following steps of: a, acquiring soil profile information; b, determining a surface soil texture allocation coefficient t; c, dividing construction sections; and d, performing layered construction. Compared with the conventional land reclamation technology, the method has the advantages that: the method effectively maintains original structural layers of soil profiles, protects fertile surface soil resources, and maintains the ecological environment of the soil; in the method, the quality of reclaimed soil is higher; and for cultivated land with poor texture (sandy or clay)
