Paper presented at the 58th U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2024
Paper Number: ARMA-2024-1069
... ABSTRACT: The rock mass strength depends on a combination of non-persistent discontinuities and blocks of rock mass. Currently, the representation of the strength for slope stability analysis includes the joints sets (structural domains) with preferential orientations that generate unfavorable...

..., the results of the unconfined compressive test do not agree with the strength models of the classical strength formula because the strengths at certain orientations of cleats appear much higher than the estimation by the classical solution. The influence of non-persistent cleats on coal strength is, thus...
