The article presents the results of the studies aimed to develop a procedure for selecting dynamic ground support for mining under rockbursting conditions. The dynamic ground support means a system capable to withstand loads generated by dynamic phenomena of rock pressure. Such support system includes rock bolts and surface reinforcement elements having increased load-bearing capacity, capable to deform but not break. One of the methods to abate rockburst aftereffects is the dynamic support installation to withstand high-magnitude phenomena of rock pressure. The optimal dynamic support should be able to prevent rock fall under rockbursting while being comparatively inexpensive and readily installable. The support selection procedure presented in this article is recommended for mining operations in hard rock mass under rockburst hazard. Different kinds of rock bolts and surface reinforcement elements are analyzed at the stage of mine planning and design from the viewpoint of energy absorption and deformability. The proposed approach is recommended for the dynamic ground support design for various systems of mining—open stoping, stoping with backfilling and mining with caving. In difficult ground conditions, in case of increased rock pressure, abundant inflow of ground water, or heavily jointed rock mass, the ground support design should be adjusted based on the geotechnical audit of rocks and using dedicated programs.
