Soil Reclamation Models by Soil Water Infiltration for Refuse Dumps in Opencast Mining Area of Northern China

The water infiltration rules of five different homogeneously or heterogeneously-constructed soil samples were determined to select the best construction module for refuse dump reclamation in opencast mines Shanxi-Shaanxi-Inner Mongolia energy circle. Five treatments, including three homogeneous consisting sandy soil, Montmorillonite-enriched sandstone, and sand-Montmorillonite-enriched sandstone mixture, together with two heterogeneous composed + − mixture (7:3) soil. Three replicates each treatment prepared indoor pillars measure process by auto-recording geometry, investigate features various configurations testing their rate, cumulative capacity, wetting front migration, profile content, evaluate newly constructed natural conditions research area. experiment demonstrated that addition into significantly slowed down infiltration, especially soils. Traditional models perfectly simulated soils which capacity could be segmentally fitted Kostiakov model linear model, a power function. Compared samples, reduce direct surface runoff deep percolation, is an idealized structure reconstruction coal mine dump.
