Modeling of Elastic Oscillations in a Fractured Rock Mass ahead of an Underground Roadway Face

The propagation of vibrations in a rock mass arises from sources such as explosions, equipmentinduced vibrations, seismic activity, and other dynamic processes.During the interaction of a cutting tool with a coal seam, the rock undergoes compression and deformation, generating stresses in the contact zone.These stresses initiate the propagation of elastic waves within the rock mass.As these waves traverse various geological structures, they undergo reflection and refraction, acting as unique carriers of information about the rock condition.Such waves can serve as indicators of dynamic
