摘要：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 the 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.
