Abstract
Mining is one of the activities that require large areas of land for the storage of sterile rocks resulting from the extraction of useful mineral substances. Waste dumps are wide-spread, are unpleasant components of the landscape causing a negative visual impact, the modification of ecosystems and their functions, environmental pollution (depending on their content, it can result atmospheric pollution by entrainment of dust particles and powders by winds, generation of acid waters, land and soil pollution with trace elements, etc.), and may present risks for the objectives in the area as a result of the sliding potential. The waste dumps consisting of inert rocks like sands, clays, and dust in different mixtures, which present various degrees of aeration and permeability and which lack the fertility given by organic matter, need proper interventions and works to support the development of more valuable plants and to reintegrate them into the natural landscape. The research presented in this paper aims to identify the necessary steps in order to accelerate the pedogenesis process on mining dumps and, as a result, a logical scheme type method was developed that could be easily applied to any type of mining dump. Also, the logical scheme was applied and verified through an experimental study carried out at the level of the interior dump of North Pesteana open-pit from Rovinari mining basin, Romania.
