The GG-1 shaft is an investment of strategic importance for copper mining in Poland related to the operation of a new copper deposit in the Głogów Głęboki-Przemysłowy region.
GG-1 is the 31st shaft built by PeBeKa S.A. in the Zagłębie Miedziowe at the request of KGHM Polska Miedź S.A.
Construction of the GG-1- shaft in progress
Investor: KGHM Polska Miedź S.A.
Duration: 2013-2021
Additional technical data:
• The shaft in Kwielice will ultimately be the deepest object of this type in the entire Zagłębie Miedziowe. (Depth of shaft: 1351 m).
• The first bucket of ore left the shaft on December 13, 2013.
• 466 reinforced concrete tubing rings were installed in the shaft. Each ring consists of fourteen segments, which weigh from 2 to 5 tons. In total, the entire tubing housing installed in the GG-1 shaft weighs approx. 25,000 tons!
• The GG-1 shaft will be a downcast shaft used for transporting materials and people, and an air-conditioning station and main dewatering pump chamber will be built on the surface.
• The GG-1 shaft has been equipped with a cascade drainage system to protects the shaft against flooding. The last such system, but of course not so modern, was built in the SG-2 shaft more than twenty years earlier.
