Reclamation of heaps and industrial sites built in the region of Madjarovo mine (Bulgaria)
Venera Tsolova, Ivaylo Kirilov, Martin Banov
Abstract: The Madjarovo open pit for lead-zinc ore extraction is located in the land of Madjarovo city, Kardzhali District. The reclamation of technogenic territories build as a result of mining is legally carried out in two stages – (mine-) technical and biological reclamation. This article presents an option for technical and biological remediation of heaps and industrial sites built in the region of Madjarovo mine, based on the results of their pedogenic and agro-eco-chemical studies and good practices in the field of reclamation. The results show that in order to achieve an optimal restoration of natural landscape, a number of activities have to be carried out in these territories. In general, they are:
• Clearing the disturbed territories from constructional and other wastes and leveling.
• Amelioration to reduce the redistribution of metals-pollutants in environment.
• A topsoil formation by pilling of geological materials with appropriate physicochemical characteristics for complete
alignment and improvement of anthropogenic territories.
• Grassing with suitable vegetation.
