Results of recent experimental studies on the strength of rocks under axisymmetric and asymmetric true triaxial state of compressive stresses are presented in the paper.
This component consists of two profiled rock bolt washers, two disk springs, and three guide bars. The article discusses results of static loading test of the expansion shell rock bolts equipped with originally budowictwie deformable component.
