The study presents the results obtained under laboratory conditions in the test rig allowing testing of the rock bolts at their natural size, as used in underground metal ore mines.

Sign in to gemoechanika. Springer-Yerlag, Berlin and Heidelberg Using samples of a certain sandstone, the effect of not only confining pressure but also, independently, minimum and interrnediate principal stress was determined. The article discusses results of static loading test of the expansion shell rock bolts equipped with originally developed deformable component.

Effect of the intermediate principal stress on strength and deformational behavior of sedimentary rocks at the depth shallower than m. The rock bolt was loaded statically until its budownictaie loading capacity was exceeded.

Pintabona and Smithson M. Fracture and flow of rocks. There were two phases of displacement observed during the static tension of the rock bolt which differed in their intensity. The stiffness of the yielded and stiff bolts was empirically determined, including stiffness parameters of every individual part deformable component, steel rod.

Rockbolting and Rock Mechanics in Mining, Aachen, The basic type of rock mass reinforcement method for both preparatory and operational workings in underground metal ore mines, geomechaniika in Poland and in different countries across the world, is the expansion shell or adhesive-bonded rock bolt. In “Tectonophysics of Mining Areas”, edited by A. The construction materials ensure that at first the springs under loading are partially compressed, and then the rock bolt washer is plastically deformed.

The rock bolts tested were installed in blocks simulating a rock mass with rock compressive strength of geomecganika MPa. Rossmanith, Balkema, Rotterdam A case study in southern Italy, Bulletin of Earthquake Engineering,9 4
