摘要：
The new designs of tools for hard rock mining are presented, as well as the results are cited for the experiments on the laboratory stand constructed in the University of Mining and Metallurgy of Krakov. The tests were conducted by cutting artificial rock samples with the use of standard and new mining facilities. The rotary picks and non-symmetric disc cutters of new structures were applied.
