existing facilities for deviation of the Krivelj River in 3D format<br />
3. TECHNICAL DESCRIPTION OF<br />
THE NEW FACILITIES FOR<br />
DEVIATION OF THE<br />
KRIVELJ RIVER<br />
To realize the plans of potential development<br />
the Veliki Krivelj Mine, which<br />
include the following period until 2050, it<br />
is necessary to meet a number of preconditions,<br />
among them is certainly the<br />
construction of facilities for relocation the<br />
Krivelj River in the zone of flotation tailing<br />
dump Veliki Krivelj.<br />
For further exploitation of this mine,<br />
the construction of the following capital<br />
facilities is anticipated:<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, it is necessary to construct the<br />
following hydrotechnical facilities:<br />
- drainage system for Dam 4<br />
- pump station of drainage water for<br />
Dam 4<br />
- system for supply of pulp and gravitational<br />
power of hydrocyclone on<br />
Dam 4.<br />
In addition to the construction of these<br />
facilities, it is necessary to install the new<br />
pipelines for return the feedback water<br />
from the lake of Field 3 to the tanks of the<br />
Krivelj Flotation Plant or connection into<br />
the existing system of feedback water and<br />
to make the relocation of pipeline for<br />
drinking water Surdup - Bor.<br />
