Summary:

Copper mineralization in the Lubin-Malomice concession covers an area of 70 km2 at depths of 638 m to 1,006 m below surface. When fully developed, a typical ore profile consists of (in descending order):
- Calcareous dolomite.
- Streaky dolomite, generally banded.
- Clayey dolomite.
- Cupriferous Shale, bituminous in the lower part and dolomitic in the upper part; upper interface sharp or transitional; thickness variable, generally 30 cm to 50 cm.
- Boundary Dolomite; grey micritic dolomite, about 5 cm thick.
- White Footwall Sandstone, fine-grained with calcareous cement passing downwards into clay cement; thickness 8 m to 10 m of which the uppermost 2 m to 3 m may be mineralized.

Locally, a second mineralized horizon is encountered in the White Footwall Sandstone, generally separated from the Cupriferous Shale by a 2 m to 3 m thick interval carrying only traces of sulphide mineralization. Because of its small lateral extent and patchy occurrence, this horizon has no economic importance, except where copper mineralization extends upwards through the whole interval to the Cupriferous Shale. The base of copper mineralization in the White Footwall Sandstone is sometimes marked by the so-called “bornite smear”, in which the copper content can attain 3% to 4% over a thickness of as much as 10 cm to 20 cm.

There are two contrasting structural domains within the combined Lubin and Malomice mining area. The southern part of ........

Summary:

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 loade ........
