As opencast coal mining is a temporary use of land, there is a need for the restoration of mine dumps after completion of mining activities. Vegetation on the mine dumps is beneficial to control the coal dust dispersion, soil erosion, sedimentation, and ultimately improve the soil quality ( Mukhopadhyay et al., 2017 ).
