Abstract. Subject of this research is geotechnical parameters of the rocks. Different studies of impact of geomechanical process intensification on the rock geotechnical parameters were ana-lyzed, and basing on the findings on impact of mining activity intensification on operation of geo-mechanical system "rocks - supports and safety structures", the following patterns of the rock beha-vior were established: in transversely isotropic visco-elastic fractured rocks, length of the console overhanging over the open area of the face is directly proportional to its capacity and rock elasticity modulus and is inversely proportional to the depth of mining operations, viscous properties of the coal-rock mass and degree of its heterogeneity, and increases, by close to linearly law, with in-creased rate of the face advance; value of the caving critical step increases parabolically with the growing rock tensile strength; road-support increment in the area of the face roof fixation (face-end) is directly proportional to the roof capacity, length increment of the freely overhanging roof console and rate of face advance.

Keywords: intensification, geomechanical processes, geotechnical parameters, rock massif.
