With the development of the social economy, the depth of underground constructions is increasing in the fields of mining engineering, tunnel engineering, hydropower engineering, nuclear waste storage engineering, and underground protection engineering. Mining engineering, for instance, in the world, nearly 200 metal mines with mining depths of more than kilometers, and the deepest mine has reached more than 4000m underground. The excavation of engineering rocks at high depth is subjected to the state of complicated circumferential stress, for example, the high in-situ stress, the high ground temperature, the high hydraulic pressure (high gas pressure), and the dynamic disturbance caused by blasting and mechanical excavation. The excavation process may cause rockburst, coal and gas outburst, sudden fracture of rock mass and other dynamic phenomena, and cause serious engineering disasters. Therefore, in deep rock excavation engineering, the description of dynamic disaster response induced by excavation, the exploration of hidden disaster sources, and disaster forecasting and control have become the key technologies.
Within this context, continuous progress needs to be done to improve the safety performance of deep rock excavation engineering. Fundamental research is necessary to understand the preparatory and development phases of dynamic disasters induced by deep rock mass excavation and for developing physics-based models relating to implementing monitoring and dynamic disaster parameters. Advanced methodologies for monitoring and control of precursory information of the dynamic disasters are needed to provide realistic dynamic disasters estimates and impact forecasting. Finally, deep excavation engineering needs to be prepared to receive and respond to messages, implement good support of surround rock and eliminate hidden dangers of disasters to realize the safe and efficient implementation of deep rock mass excavation engineering.
This Research Topic aims to collect a broad range of new contributions to the development of safe and efficient deep rock mass excavation that account for a variety of aspects related to physical, methodological, and technological issues. We also wish to collect examples and case studies of deep rock excavation engineering.
Potential topics include, but are not limited to:
1. Behavior of rock masses under high in-situ stress, high ground temperature, high hydraulic pressure (high gas pressure), and other special physical conditions.
2. Precise exploration method of the deep geological structure.
3. Dynamic response characteristics of the rock support structure.
4. Surrounding rock control technology in deep rock excavation engineering.
5. Disaster risk identification and rationality evaluation model of deep rock mass excavation engineering.
6. Dynamic disaster monitoring and early warning technology for deep rock excavation.
7. Removal technology of risk factors of typical dynamic disasters.
8. Case study and examples of deep rock excavation engineering.
