The invention relates to a
screening method for replacing surface soil of strip
mine reclamation and belongs to the technical field of
land reclamation and ecological reconstruction and the field of
ecological environment materials. The
screening method includes the steps that according to detailed geological and occurrence conditions of a stripped
overburden rock-soil layer of a strip mine, firstly, the possible soil
layers for replacing surface soil are screened out primarily through analyzing geology and rock-
soil parameters of all
overburden rock-soil
layers; then, through analyzing physical, chemical, biological and environmental characteristics of all the soil
layers, the soil layer is finally screened out, wherein the soil layer is close to the surface soil in characteristic, the basic
soil properties are good, the rate of emergence is high, then a
soil conditioner is selected to be mixed with the material for replacing the surface soil to serve as replacing surface soil. According to the replacing surface soil,
solid waste treating and strip mine
waste dump reclamation can be organically combined, the dual purposes of reducing
solid waste and finishing
waste dump reclamation are achieved, the
solid waste is effectively utilized, the
ecological environment is improved, and social, economical and environmental benefits are high.
