New Rock Mechanics Testing and Measuring System at the Institute of Geonics
Janeček, Ivan ; Mishra, D.
New research tasks of the Department of laboratory research on geomaterials at the Institute of Geonics required improvement of experimental technique for investigation of the geomechanical properties of rocks and mastering of new rock testing methods as well. A new computer controlled hydraulic press with large set of adaptive accessories could meet the demands. With EU support of the project Institute of Clean Technologies for Mining and Utilization of Raw Materials for Energy Use (CZ.1.05/2.1.00/03.0082), a new Rock Mechanics System of the MTS Corporation was purchased, installed and put into operation.
The history of measurement of rock mechanical properties at the Institute of Geonics AS CR
Konečný, Pavel ; Blaheta, Radim
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.
