Effect of the intermediate principal stress on the failure of a foliated anisotropic rock.
Metoda badania w temperaturze otoczenia, The article discusses results of static loading test of the expansion shell rock bolts equipped with originally developed deformable component. In “Tectonophysics of Mining Areas”, edited by A.

Pintabona and Smithson M. Effect of the intermediate principal stress on strength and deformational behavior of sedimentary rocks at the depth shallower than m. The stiffness of the yielded and stiff bolts was empirically determined, including stiffness parameters of every individual part deformable component, steel rod. Fracture of anisotropic rocks under general triaxial compression.
Doctoral Thesis, Hokkaido University, Sapporo Faulting in an anisotropic, schistose rock under general triaxial compression. A new true triaxial celi for testing mechanical properties of rock, and its use to determine rock strength and deformability of Westerly granite. The disk spring and disk washer material differs in stiffness. Empirical Rock Failure Criteria. The basic type of rock mass reinforcement method for both preparatory and operational workings in underground metal ore mines, both geomechabika Poland and in different countries across the world, podziemntm the expansion shell or adhesive-bonded rock bolt.
Faulting of a foliated rock in a general triaxial field of compressive stresses. The construction materials ensure that at first the springs under loading are partially compressed, and then the rock bolt washer is plastically deformed.
Effect of the triaxial stress system on the failure of dolomite and limestone.

There were two phases of displacement observed during the static tension of the rock bolt which differed in their intensity. This component consists of two profiled rock bolt washers, two disk springs, and three guide bars.
Rockbolting and Rock Mechanics in Mining, Aachen, The relationships between the geometric parameters and specific strains or displacements of the bolt rod were described, and the percentage contribution of those values in total displacements, resulting from the deformation of rock bolt support components washer, thread and the expansion shell head displacements, were estimated. Dilatancy of rocks under general triaxial stress states with special reference to earthquake precursors.
