Abstract
An ecological reconstructed sponge structure of a strip mine dump includes a three-layered sponge ecological structure arranged on a groundmass layer of the dump. From bottom to top, the three-layer sponge ecological structure comprises a water-resisting layer, a water-containing layer and a topsoil ecological layer. A thickness of the water-resisting layer is 100˜200 cm, a permeability coefficient of the water-resisting layer is 0.35˜0.7 m/d, and a degree of compaction is 1200˜1400 KPa. A thickness of the water-containing layer is 150˜250 cm, a permeability coefficient of the water-containing layer is 10˜20 m/d, and a degree of compaction is 800˜900 KPa. A thickness of the topsoil ecological layer is 40˜60 cm. Soil layer thicknesses and water content may be monitored through a ground penetrating radar.
