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 100200 cm, a permeability coefficient of the water-resisting layer is 0.350.7 m/d, and a degree of compaction is 12001400 KPa. A thickness of the water-containing layer is 150250 cm, a permeability coefficient of the water-containing layer is 1020 m/d, and a degree of compaction is 800900 KPa. A thickness of the topsoil ecological layer is 4060 cm. Soil layer thicknesses and water content may be monitored through a ground penetrating radar.

A process and associated system for the improved reclamation of disturbed lands (e.g., mined lands) is disclosed. In particular, the system including a dewatering cyclone, a screw classifier, and a dewatering apparatus (e.g. a dewatering belt) arranged in series to enable rapid and cost effective dewatering of slurries containing dilute clay and sand tailings to create an improved engineered reclamation material (ERM). The ERM formed by the controlled combining of dewatered sand tailings with dilute clay slurry and with a flocculant and overburden. The ratio of clay:sand: overburden of the ERM may be achieved by balancing the solid content (Cw) and water content (1Cw) materials of the clay slurry, sand tailings and overburden. In some embodiments, the system may include at least one additional component, such as, for example, static screen(s), centrifuge(s), vibrating screens, drum screens, belt screens, belt filters, and/or other liquid-solid separation devices.
