Springer-Yerlag, Berlin and Heidelberg The basic type of rock mass reinforcement method for both preparatory and operational workings in underground metal ore mines, both in Poland and in different countries across the world, is the expansion shell or adhesive-bonded rock bolt.
The study presents the results obtained under laboratory conditions in the test budowictwie allowing testing of the rock bolts at their natural size, as used in underground metal ore mines.

Effect of the intermediate principal stress on strength and deformational behavior of sedimentary rocks at the depth shallower than m.

Metoda badania w temperaturze otoczenia, This component consists of two profiled rock bolt washers, two disk springs, and three guide bars.
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. Using samples of a certain sandstone, the effect of not only confining budownictwir but also, independently, minimum and interrnediate principal stress was determined.
Behavior of a sandstone under axi- and asymmetric compressive stress conditions.

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.

Pintabona and Smithson M.
Dilatancy of rocks under general triaxial stress states with special reference to earthquake precursors. The stiffness of the yielded and stiff bolts was empirically determined, including stiffness parameters of every individual part deformable component, steel rod. There were two phases of displacement observed during the static tension of the rock bolt which differed in their intensity.
