ABSTRACT
This paper details the experiences of national copper ore mining associated with mechanized rock excavating systems. In particular, the machines used, technological solutions, efficiencies, and problems related to their implementation to underground copper mining conditions on Fore-Sudetic Monocline are discussed. Beginning from the experiences of „Konrad” mine in the Old Copper Basin where cutter-loaders type WŁE-50S were used - and ending with the ongoing tests with the Caterpillar ACT longwall shearer in the „Polkowice-Sieroszowice” mine. The implementation of mechanical excavation systems in KGHM’s mines has not reached a successful level thus far, but the results achieved during the previous attempts are promising. The roadheaders used while excavating the mining drifts achieved very good results considering the given mining-organizational conditions.
