Fig. 4. Disposition of facilities for relocation the Krivelj River in the zone of<br />
flotation tailing dump Veliki Krivelj large Krivelj<br />
Implementation the development plans<br />
of the Veliki Krivelj Mine, in the next<br />
forty year period, involves filling a number<br />
of pre-conditions, including the very<br />
important one as the construction of capital<br />
facilities for relocation the Krivelj<br />
River in the zone of flotation tailing dump<br />
Veliki Krivelj, as follows:<br />
- tunnel for deviation the Krivelj River<br />
in the zone of Field 2<br />
- tunnel for deviation the Krivelj River<br />
in the zone of Field 3<br />

- connections (tunnel - collector) between<br />
the existing tunnel for the Bor<br />
River and a new tunnel for the<br />
Krivelj River<br />
- collector for introduction the Saraka<br />
Stream into a new tunnel of the<br />
Krivelj River.<br />
Also, to avoid a possible formation of<br />
flooding wave upstream of Dam 4, as the<br />
consequence of a tunnel construction<br />
through Field 3 of the flotation tailing<br />
dump and threatening the open pit,
