ASPECTS REGARDING THE CONSOLIDATION - INJECTION WORKS FOR THE OF MIHOIEŞTI DAM.

The issues dealt with in this paper consists of the submission the optimal solutions for the consolidation of Mihoiesti dam, taking into account the problems that occurred during the exploitation of this objective, and site conditions. 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. Sealing-consolidation works consist in the execution of the drilling injection to create a veil that extends seal on both slopes. [ABSTRACT FROM AUTHOR]
