From the perspective of economic and safety, the mechanical stability of a waste dump is crucial; therefore, re-vegetation is considered to be the most pertinent and eco-friendly approach to achieve this goal. However, not many studies address this concern and support the type of vegetation to be carried out on these waste dump slopes. This study has, therefore, explored the possibilities of using local species for the mechanical stability of the waste dump in surface iron ore mine for long-term protection of the environment. Commonly available local species are considered as prospective candidates that can adapt quickly to the climate and fit into the ecosystem, and an in situ test was used to calculate the shear strength of the vegetated waste dump. This test used a customized shear box (0.15 m × 0.15 m × 0.15 m) to evaluate the increased mechanical stability of the vegetated waste dump on the surface iron mine. From the analysis of in situ field data, it is concluded that the mechanical stability of waste dump has significantly improved with a possibility of extending its role toward maintaining long-term stability.
