Evaluation of the performance of yielding rockbolts during rockbursts using numerical modeling method
Abstract
Highlights: (1) Energy-absorption capacity of yielding rockbolts in rockbursts is evaluated. (2) Rock deformation and rockburst damage are quantitatively assessed. (3) Performance of yielding rockbolts in weak and strong rockbursts is studied. (4) Effects of floor support and cable bolts on controlling rockbursts are discussed.
