This cluster of papers focuses on the study of wave propagation, rock mechanics, and geomechanical processes in block media. It includes research on seismicity induced by mining activities, modeling of elastic wave propagation, analysis of pendulum waves in stressed geomedia, and the performance of drilling equipment in rock stiffness. The cluster also covers topics such as hydraulic drilling, geomechanical assessment, and the influence of nonmetallic inclusions on percussive machine endurance.
