The fatal consequences of open-cast mining are first and foremost the considerable degradation of the earth's surface. Soil disturbed during mining operations must be rehabilitated in line with the progress of the extraction work, to promote environmental protection. Restored areas contribute to the oxygen balance, rainfall and soil regeneration. The aim of this work is to highlight the development techniques used in areas affected by mining operations. To carry out this research work, we used technical restoration, which consists of rehabilitating disturbed soils with a view to their subsequent use for the needs of the population, and biological restoration, which consists of implementing appropriate measures to protect the environment and allow flora and fauna to flourish. This includes creating a fertile layer after logging, developing nurseries and seedlings, transplanting and protecting wooded areas. For forest and fruit restoration in our study area, we have planned: 395,760 cashew seedlings because of their resistance to unfavorable climatic conditions and 168,375 acacia seedlings for firewood, charcoal, furniture and construction. Mine rehabilitation is a more complex discipline, involving the use of native plants to mimic the natural ecosystem, rather than simple revegetation actions. In general, complete reclamation is impossible, but careful restoration and rehabilitation can create a favorable ecosystem.
