Abstract PDF References Article Recommendations Abstract 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 budlwnictwie across the world, is the expansion shell or adhesive-bonded rock bolt.

Sign in to annotate. Behavior of a sandstone under axi- and asymmetric compressive stress conditions. Using samples of a certain sandstone, the effect of not only confining pressure but also, independently, minimum and interrnediate principal stress was determined.

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.
