Terminology and definitions. Stabilization measures of underground openings. Technology, mechanical behavior and load-bearing capacity calculation of rock reinforcement, rock support, pre-reinforcement and pre-support measures. Support of rock wedges. Stratified or laminated rock roofs: mechanical behavior, suspension, reinforcement, behavior after cracking. Stress and deformation analysis around underground openings in: massive rocks, blocky rocks, very blocky and fragmented rock masses, weak rock masses and squeezing rocks. Interaction of neighboring openings. Analytical solutions and numerical simulation methods. Rock–support interaction: sequential excavation and support installation, rock mass de-confinement and convergence, support reaction. Convergence-confinement curves and interaction with the support for elastic, elastoplastic, brittle and time dependent rock mass behavior. Analytical solutions and numerical simulation methods for rock-support interaction analysis. Design of support systems in dynamic conditions: explosive rock behavior, response of support measures to dynamic loads, selection of support measures.
