The presented paper presents another results of the rocks fracture toughness measurement. The influence of the loading velocity on the fracture parameters was investigated. The loading velocity was continually changed in values 1; 0,1 a 0,01 mm/s. The measurements were realized on selected rocks in the laboratory conditions in the Institute of Geonics AS CR.
