DETERMINATION THE IMPACT ZONE OF OPEN PITS ON A
LEVEL OF GROUND WATER IN THE CEROVO ENVIRONMENT **
Abstract
Mining works in Cerovo represent the potential risk to the water regime changes in the environment
and their pollution with water from the open pits (Figures 1 and 2) that contain various
chemical substances in the form of solution. A range of effect the excavated parts of copper ore
deposit in Cerovo on ground and surface water within the exploration area of open pits is very
important for organization the land protection in the environment from dryness, and the open pits
from the water inflow (Figure 1). This paper specifically analyzes a possibility of evaluation the
range of ground water level changes in the surrounding soil caused by mining of copper ore deposits
in Cerovo.
Key words: open pit, environment, ground water, copper
INTRODUCTION
In the area of Cerovo, 20 km north of
Bor in hydrothermal altered zone, the ore
field Mali Krivelj – Cerovo is located with
copper deposits: Cerovo Primarily, Cerovo 2,
Drenovo and Kraku Bugaresku - Cerovo –
Cementacija 1. Three open pits (Figure 1) are
predicted for opening in this area with reconciled
dynamics of continuous production of
7.5 million tones of copper ore annually. According
to the business plan, the opening of
open pits is in the following order:
1. First, the existing open pit Cerovo–
Cementacija 1 is expanded (Figure 1),
opened in 1993 on the Kraku Bugaresku
locality. The open pit mining has lasted
until 2002. Pre-explored copper reserves on
the same deposit allow the expansion of this
For the needs of this open pit opening,
it is necessary to carry out a relocation the
part of the railway Bor – Majdanpek, in
length of 1200.0 m with the railway station,
a relocation of long-distance power
line and river bed of the Cerovo river creating
the appropriate tunnel which will
implement the Cerovo river into the river
bed of the Valja Mare river.
Figure 1 shows the open pit Kraku
Bugaresku – Cementacija 1 that is expanded
and deepened because the additional
explorations have established a significant
ore quantity that is minable.
Figure 2 shows the river after inflow of
leaching solutions from the open pit C1.
