ABSTRACT

The accumulation Mihoiesti was to ensure, primarily, the water in the area of mines
Apuseni Mountains - Rosia Poieni use fall created to produce electricity and other uses
of the river basin Aries. Waiving further develop water requirements for the operation
of copper Rosia Poieni, imposed, as in the current situation, accumulation conducted to
act as temporary accumulation over a period of time greater, with some implications for
the function. Currently, the dam does not meet the conditions of safety in operation,
with large water waste-way undersized and there is still unfinished work. Dam with a
mask made in an interim arrangement, with some areas infiltrations, and the extension
version, constituting a threat to downstream areas. To resolve this problem, it is
proposed to achieve the work for the operation of accumulation Mihoiesti as permanent
accumulation. The use of the lake will flood wave attenuation, with important effects on
the probability of occurrence greater than 2 %, which states as specialists appear every
50 years. The coffer dam was executed in a first step to achieve an accumulation of a
volume of 6.25 million m3, of which 0.25 million m3 volume warping.

Keywords: accumulation, dam, injection - consolidation, security, stability.
