Methodology of Testing the Strength and Deformational Properties of Rocks from LGOM Mines under Triaxial Stress Conditions Authors: J. Lis, P. Kijewski
The paper presents the laboratory equipment used in triaxial tests carried out at the Rock Mechanics Laboratory of the Mining Department, the KGHM CUPRUM Ltd Research & Development Centre. The equipment for triaxial tests at confi ning pressures of up to 250 MPa which allows for the determination of the strength and deformational properties of rocks is described. Using the results of the tests, the criteria for rock failure under compression, shear, tension and bending were determined. An attempt to monitor the propagation of cracks in rocks under hydrostatic pressure up to 60 MPa was also undertaken. |
