mainly from compression tests, or through the particular triaxial experiments commonly known as Conventional
Triaxial Compression (CTC). The procedure of CTC test usually consists of initial compression up to isotropic
pressure imitating e.g. a component of geostatic stress at a given depth, and subsequent application of
additional axial loading, which can be a model of anisotropic stress conditions or differential stresses originating
from inhomogeneities or movement of surrounding rock masses. This CTC test, however, cannot always portray
the in-situ conditions. For example such axial compression does not reflect the real stress paths during the rock
burst. More appropriate experimental model for the phenomenon is axial stress reduction inducing axial
extension in test named Reduced Triaxial Extension (RTE). Stress paths representing axial extension are also
important in case of core disking. In addition to CTC and RTE paths, the next complementary paths can be
considered: Conventional Triaxial Extension (CTE) or Reduced Triaxial Compression (RTC) using increasing or
decreasing the lateral stress respectively. This work discusses the experimental methodology and technical
solutions prepared for realization of several special loading paths in laboratory triaxial experiment.
