Project for increasing the structural safety of the “Chelopech” tailings storage facility
Period of implementation
Glavbolgarstroy’s role in the project
Nature of works
earthworks at the southern wall of the "Chelopech" tailings storage facility
The construction was conducted in a phased manner, without disrupting the facility's ongoing operations. Ground facilities, elements of the control and measurement system on the southern wall, pipelines, and other adjacent infrastructure were sequentially developed. Various preparatory tasks, such as excavation-filling work for temporary roads and overloading, concrete work, and drilling, were also carried out.
These completed activities mark the fourth and final phase of the site's implementation. They encompass the establishment of a drainage layer along the slopes of the southern wall, bottom drainage along the gully leading to the retaining wall, drainage strips, and drainage ribs. Additionally, the embankment of the main wall was reinforced, and a comprehensive control and measurement system for the wall, consisting of piezometers and measuring marks, was implemented.
