Analysis of Possibilities of Reclamation Waste Dumps after Coal Mining

In the Ostrava-Karvina coal district, approximately 281 dumps and 46 waste dumps are located. These are anthropogenic embankments of gangue formed at different times during the nearly 200-year tradition of coal mining in Czech parts in Upper Silesian Coal Basin. The aim of this publication is to analyse the possibility of reclaiming these waste dumps. Basic boundary condition of reclamation gangue material is composition and shape of the embankment. The publication defines the different possible shapes of gangue bodies and the possibility of their rehabilitation. Waste dumps are various shapes, it may be a conical waste dump, pile type shape, board shape, shape of the terrace, shape of slope, ridge shape, straight shape, or may take the form of flat coverings. Reclamation types are closely tied to land use planning. Waste dump bodies can remain in their original deposit with no or minimal intervention on its surface as needed. Another possibility represents the partial excavated waste dump to the body and then modification of its geometry according to the needs of the land use planning. Option, how reclaim territory include also the variant of full excavation of waste dump body and completely terrain reclamation. (C) 2015 Published by Elsevier B.V.
