Mixing these materials will result in an increase in the amount of coarse particles in the minesoil, allowing more infiltration and percolation of rainfall, decreasing surface runoff, and hence reducing erosion and sedimentation. Also, since more rainfall enters the minesoil and moves deeper, there is more moisture available for plant growth.
