Abstract
Mine Toranica - Kriva Palanka for exploitation of lead and zinc, has taken certain activities to
improve and qualify the tailing dump for further exploitation, as well as activities for environmental protection
from the flotation tailing dump.
The drainage carpet and the gabion wall with height of 5 m (previewed for constructing in next phase) will
constitute a whole which will collect the filtrate and spring water from the sand dam through drainage carpet
and through polypropylene pipes, thus the waters will be redirected from the flotation tailing dump, therefore the
sand dam stability will be improved and will prevent the infiltration of higher amounts of infiltrate water in the
subsoil and the side channels in the valley of the river Kriva Reka.
The drainage carpet is designed by one main leg that is parallel to the collector with length of approximately
50 m and two legs, left one (with length of app. 28 m) and right one (wit length of app. 15 m). The drainage
carpet is approximately in shape of flipped letter “Y”.
The drainage carpet is designed in the way that firstly on the bottom 300 gr/m2 geotextile with thickness of
3,00 mm is placed, then above this layer rough geo-membrane HDPE with thickness of 2,00 mm, and above the
geo-membrane again geotextile 300 gr/m2 with thickness of 3,00 mm. Above the geotextile filter layer that
contains 3 layers with fractions 460 mm (2 layers) and 18 mm (one layer). This filter material should be
covered with the above mentioned geotextile 300 gr/m2 with thickness of 3,00 mm.
The positive impacts of this project will have long-term environmental effect, to prevent possible instability of
sand waves and extended lifetime of safe exploitation of hydro tailing dump.
