Estimation of Rock Burst Grades Using Rock Mass Strength
, 2020 The traditional rock burst estimation method is usually based on the σc (rock strength) in practice, while the actual occurrence of rock burst depends more on the structure and strength of the rock mass. In this work, the actual rock bursts occurred in a

Energy sources of rock burst and the influence of the surrounding rock mass
, 2023 The kinetic energy for rock ejection in a rock burst event is converted from the strain energy stored in the burst rock, a portion of strain energy released from the surrounding rock mass and a portion of seismic energy transferred from fault-slip ...
