摘要：
The paper describes the investigation results on specific strain energy in hard rocks (urtite, ijolite and apatite-nepheline ore) under uniaxial compression, tension and triaxial compression. The ways of strain energy accumulation have been shown in the investigated rock samples under different loading modes on the pre-pick and pick stage. The connection between energy accumulation capability of the rocks and their strength and deformation characteristics has been established. The investigation results have been examined in respect to forecasting rockburst hazard in the hard rock mass. (C) 2017 The Authors. Published by Elsevier Ltd.
