Lab activity

Laboratory of mining mechanization and dimension stone conducts research on the physical and mechanical properties of rock (fracture toughness of rock, rock cuttability, linear thermal expansion coeffi cient, rheological properties of rocks), technological properties of conveyor belts constructional parameters and physical and mechanical properties of steel wire ropes. The Laboratory also conducts fi eld measurements of stresses and deformations in steel and concrete structures (large diameter steel pipes, steel oil rig containers, concrete tunnel linings etc.). All tests are performed in accordance with the appropriate Croatian and European standards and methods suggested by the International Society for Rock Mechanics (ISRM).
