   The rock testing and evaluation of parameters for description of rock behaviour is an important part of the research at the Institute of Geonics AS CR since its foundation as an independent institute of the Czechoslovak Academy of Sciences in 1982. Focusing on mechanical testing, the first testing device, the hydraulic press EDZ 100H made in GDR with maximum force 1000 kN, was acquired in 1980, when only a branch of the Mining Institute existed in Ostrava. This equipment was substantially extended in the eighties by two "small" mechanical presses FPZ 100 (max. force 100kN) and FPZ 10 (max. force 10kN) purchased in 1987 from GDR. But a really great progress came with the mechanical press ZWICK 1494 (500 kN) controlled by computer with a possibility of recording and processing the data. This press was bought from ZWICK Ulm (FRG) in 1985. The deformation measurement was realized by the dial test indicators.
   The described equipment was used for rock testing with focus on elastic behaviour and uniaxial strength limits, which were required for solving engineering problems mostly related to the coal mining.
