Coal is a valuable resource. It provides a significant amount of
the World's energy supply and it is the basis for many industries.
However, in areas where coal lies close to the Earth's surface and
has been exploited by open cast tech niques, radical alterations of
landscape and significant impacts on the envi ronment have
occurred. This report was prepared to provide guidance to those who
are responsible for the prevention of environmental effects from
surface mining and for the restoration of the mining areas.
Environmental problems of surface coal mining and restoration of
the mine sites are discussed in the re port. Particular attention
is given to Eastern Europe, which continues to be a major centre of
opencast lignite mining. Reclamation of mined lands for for estry,
agriculture and wildlife is briefly discussed. However, the shear
volume of coal removed from many mines in Eastern Europe is so
vast, that there is often insufficient overburden material to
refill the pits. Consequently, the main focus of this report is on
the creation of lakes in these former surface mines. Many problems
have to be overcome in creating healthy lakes for recreation or
wildlife. Guidelines for treating water quality problems and
further devel opment of lakes are provided. Techniques for dealing
with acidic, waters, eutrophication and contamination are
discussed."
