    The soil dumping technology used determines the development of the reconstructed soil horizon. After mining disturbs soil horizons, RMS undergoes a self-restoring process. The younger minesoils develop through interactions between climate, living organisms, and the land surface, over time (Jenny, 1941; Sencindiver and Ammons, 2000). These soils ...

    The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the material affects the angle of repose; smooth, rounded ...
