Protection Technique of Support System for Dynamic Disaster in Deep Underground Engineering: A Case Study

Sustainability, 2023
During excavation in a deep tunnel, dynamic disaster is an extremely severe impact failure. The necessity of an energy-absorbing support system is analyzed for different characteristics of dynamic disaster (rockburst) failure. The energy-absorbing support system design includes a combination of early-warning, energy-absorbing bolts, and other ...
