In Polish underground copper ore mines belt conveyors are the most common transport facilities. In KGHM Polish Copper SA there are over 100 km of belt conveyors. To increase reliability of the transportation system there are built numerous ore bunkers ensuring continuity of the excavation during 5 working days of the week and on weekends, during which ore bunkers feed processing plants. In addition, some conveyors were built as reverse ones what in cases of emergency can provide alternative routes to supply ore to...

The effectiveness of enrichment process of run-of-mine copper ore (at KGHMпїЅs ore enrichment plants) depends on the selection of appropriate working parameters of processing machines which are customized mainly to fit the fed rock type. Therefore, the knowledge of lithological composition of run-of-mine copper ore fed to the ore processing plant can significantly improve the effectiveness of the enrichment process. The issue of optimization of enrichment processes with the help of the use of in-situ sensor techno...

Processing of copper ore strongly depends on its parameters, therefore the more accurate identification of them should improve the process efficiency. The ore exploited in the KGHM underground mines in Poland is among the most difficult for processing, mostly due to its differentiated lithological compound. It can be identified at mining faces but on the way to processing plants through the complex transportation system consisting of trucks, sectional and main belt conveyors and ore bunkers, the portions of ore ha...
