This article presents the results of works carried out by KGHM CUPRUM Sp z o.o. CBR (Research and Development Centre), on behalf of KGHM Polska Miedź SA. It is aimed at improving previously used monitoring methods of mine excavation anchor casings used in underground copper ore mines of KGHM Polska Miedź S.A. It presents a method allowing for continuous measurement and recording of load changes in instrumented anchors. This method was developed by request of KGHM Polska Miedź S.A. Particular attention was paid to issues related to the impact of dynamic changes of rock formation pressure on the excavation in anchor casing.
