FORME DE RELIEF ANTROPIC ÎN BAZINUL DE EXPLOATARE A LIGNITULUI ROVINARI/MAN-INDUCED RELIEF FORMS WITHIN THE LIGNITE EXPLOITATION BASIN OF ROVINARI

Abstract

The lignite exploitation field of Rovinari includes many open pits (12) that had a certain evolution and some of them do not contain lignite any longer. A consequence of the open mining is the appearance of some important modifications of the components of environment: disturbances of the lithological structure, modifications of the soil and relief, hydrographical net, vegetation etc. The man-induced relief, either the negative forms resulted from excavations, or positive ones induced by the presence of the heaps of debris are vulnerable to the action of the external factors (rainfalls, wind) that favours the development of erosion and gravitational processes. The landscape characteristic to the open pits imposes certain measures meant at supporting the re-fitting out of the area in order to reach, in time, a natural equilibrium.
