Deep Głogów (Poland)

According to estimates, deposits in the area of Deep Głogów (GG-P) constitute around one-fourth of the copper resources and around one third of the silver resources in all of KGHM’s concessions in Poland. The only way to obtain full access to these resources is the development of a deep mining system. The experience gained by experts during the Deep Głogów project is unique in the world.

The process of mining the deposits of Deep Głogów consists of three stages:

  • Stage I – gaining access to the level of 1 200 m – the creation of main mining corridors, linking the shafts containing the deposits, along with the construction of technical infrastructure necessary in the shafts, construction of the GG-1 shaft complex and the surface air cooling stations
  • Stage II – gaining access to the deposit in the Deep Głogów mining area, creation of the headings system (drifts and declines), separating the working blocks and their infrastructure
  • Stage III – preparation works – creation of preparatory workings dividing the blocks into working fields, along with infrastructure development

In 2014, drift mining was continued in order to make the Deep Głogów mining area accessible, along with the development of technical infrastructure. Sinking of the GG-1 air inlet shaft continues using tubing technology. Construction of the GG-1 shaft will be carried out in  stages with completion in 2019. It will be the deepest shaft in the Copper Belt – its targeted depth is 1 340 m, with diameter of 7.5 m. In April 2014, the first mining section commenced work in the Deep Głogów area and excavation below the level of 1 200 m was started. The deposit is being mined by two existing mines, Rudna and Polkowice-Sieroszowice. Deep Głogów’s development will allow the Company to prolong its mining operations in Poland, using its own deposits, for the next 30-40 years. During the peak period of extraction, i.e. in the years 2028-2035, production volume will amount to over 10 million tonnes of ore and 200-220 thousand tonnes of electrolytic copper, per year

Mining at such depth brought new challenges to KGHM’s engineers. For example, it was necessary to identify possible gas and geodynamic hazards. Testing with the use of seismic scanning was done – for the first time in the world on such a scale. This technique allows recognition of the structure of the rock mass with the use of seismic waves.
