Copper mineralization in the Rudna concessions occurs over an area of 40.0 km2. The distribution of the various lithological types of ore is controlled by the relief of the top of the White Footwall Sandstone, principally by the disposition of elevations (hills) and flats (depressions or valleys). From south to north, the main elevations are:
- Southern Rudna Elevation on the 900 m level : isometric dome with a size of 1 km by 1 km in plan view.
- Central Rudna Elevation between the 950 m and 1,000 m levels : 300 m to 1,000 m wide ridge elongated west-northwest with flanks sloping 10 degrees southeast and northwest.
- Northern Rudna Elevation on the 1,050 m level : west-northwest elongated ridge with dimensions similar to the Central Rudna Elevation.
- Tarnówek Elevation on the 1,100 m level, with a width of about 800 m.
- Zelazny Most Elevation, interpreted from drill intersections in the northern margin of the Rudna mining area.

It appears that these elevations are simply ridges between broad and flat valleys of preZechstein origin. This hypothesis is supported by wedging out of the Cupriferous Shale over the elevations.

There are fundamental lithological differences between the elevations and the flats. A typical profile for the flats contains all lithological units, such as the White Footwall Sandstone, Boundary Dolomite, Cupriferous Shale and Basal Dolomite. Profiles through the elevations, on the other hand, begin with the ........

Mining in KGHM Polska Miedz S.A. is performed by three mining Divisions: Lubin, Rudna and Polkowice-Sieroszowice.

The technology of mining the copper ore in all 3 mines is based on the room-and-pillar system with the use of blasting technology for ore extraction. This involves access and preparatory work, comprised of the excavation of a drift network on all sides of the site to be mined, cutting of the unmined rock mass with rooms and drifts separating a number of operating pillars, as well as extraction of the ore followed by the transport of the ore to underground dumping stations, where the large rocks are crushed and sifted through a grate, and then the crushed muck is transported to the storage areas near the shafts, from which it is transported to the surface by skip hoisting shafts.

The work related to mining of the copper ore is fully mechanised, in a 4-shift labour system, with the use of motorised mining rigs, most of which are equipped with air-conditioned cabins and systems supporting the work of the operators. Mining work is conducted in the following cycle: drilling the blasting holes with the support of motorised drilling rigs, loading blasting material into drilled holes by motorised blasting rigs, group blasting in mining divisions, followed by the ventilation of the areas blasted (from 30 minutes to 2 hours; in seismically- sensitive areas this time may be longer). The next stage involves the loading of the muck using motorised load ........
